A Design a Day – Day 314 (Giving Thanks; Part 2)

Keeping in a similar vein (giving thanks for having great support from my friends and family), here is another heart pendant idea:

This week I’ve lost two full days of work since my email and Facebook accounts were hacked.  I don’t wish this nightmare on any of you, and from what I have heard from my friends, the scam that hit me had already hit a number of my friends.  Moving forward, I still have no control over my Facebook account.   Please do not follow me there (or go to Joana Miranda Studio on Facebook) unless I give you further notice that is safe again to do so.  My email is back under control and of course my website, my shop at Etsy and my blog are safe to visit.  I am also in the process of finalizing my email newsletter account with Aweber and will be sending my fans an invitation to sign up for my newsletter shortly.  This way you can receive notification of JLM Studio news, design work, new blog posts and other goodies straight into your email inbox.

(Of course, you can still sign up to receive my blog posts via email or RSS feed.  The signups are in the blog sidebar to the right of this post.)

On the subject of goodies…Congratulations to Pam who wrote in with a thoughtful and inspiring how-to-overcome-hardship comment on my Empire Building Week 9 review post.  She will be sent the pendant pictured in that post.

(I’m certainly using her good advice this week!)

A Design a Day – Day 309 (Gold and Lapis Lazuli Earrings)

I had fun with this CAD earring design today.  Part of the enjoyment for me when I work on either CAD or hand renderings comes from imagining metal and gem combinations.  With CAD, I get the added benefit of being able to “play” around in the library of CAD files.  Selecting a metal, gemstone or background environment for that matter are just a click of the mouse away.   I think that yellow gold and lapis lazuli are a royal combination, and in this design they work well:

Come back tomorrow for more design surprises.  (I’m just as surprised usually as you are!)

A Design a Day – Day 307 (Trying to Stick with My Task List, Yet Honor My Creative Timetable)

Some of my readers have mentioned that they “miss” my hand-drawn renderings when I post computer aided designs (CAD) for my Design a Day project.  I completely understand!  When I paint, I tend to get lost in the “zone” and sometimes the results feel quite magical.

Case in point, today I set out to follow the tasks and timetable I had set out for myself.  I know from the experience of “falling off” my schedule and focusing too long on perfecting one project just how cranky and unfulfilled I can feel.  However, I was working on a detailed watercolor painting and the process of being immersed in that project ended up leaving me happy, excited and very satisfied.  Never mind that the tasks I had scheduled for 3 o’clock, 4 o’clock and 5 o’clock p.m. went unnoticed and (temporarily) fell off my list.

However, to get myself back on track and avoid feeling too guilty, I did work on another CAD rendering for tonight.  My goal with this one was to create quickly and experiment with some new backgrounds and lighting:

Are the dimensions perfect?


Have I gotten where I want to be with this yet?


Can I feel proud about checking off another one of my tasks for today?

A Design a Day – Day 303 (Stumbling Along on the Path to Greatness?)

Computer Aided Design Rendering of Geometric Diamond Cocktail Rings

I’m not totally thrilled with today’s CAD rendering for several reasons.  1st, I know that the bead-setting of the diamonds won’t work the way I have rendered them.  2nd, I want the diamonds to sparkle more, but I still haven’t figured out how to make that happen.  Lastly, even though the concept of a geometric cocktail ring is a good one, the edges of these shapes need more beveling and would probably look a lot better with milgrain detailing.  All the same, I’m excited by my progress and am having a ball with the program!


Energy and persistence conquer all things.

A Design a Day – Day 302 (Continuing on a Quest for Excellence…One Day at a Time)

I played around a bit with the background choices in my CAD rendering for today and noticed that the overall resolution improved.  These gold earrings feature bezel-set emerald cabochon stones and pear shaped pearl drops:

A Design a Day – Day 301 (Keeping the Focus Organic)

Tonight’s rendering is another CAD project:

I’m a little frustrated with my gem tools program since I can’t seem to get the gemstones (diamonds, in this case) to sparkle like I’d like.  But the issue may well be an operator (me) problem and not an issue with my program.  In any case, nothing makes me feel more alive and excited than learning, so I’m ready to tackle these new issues head on.

If any of you are familiar with the Rhino 4 and TechGems programs and want to write in and give me suggestions, I’d greatly appreciate any help!

A Design a Day – Day 300 (Home Stretch to My 365-Day Goal!)

Hard to believe that this will be my 300th day straight of posting a design on my blog!  With the eye to going out with a bang on this project, I’m challenging myself to do as many CAD (computer aided design) renderings  as possible over the next 65 days.  This will be a welcome challenge and I hope to be able to introduce a line of pieces soon from my continued efforts with CAD.  Here is a pendant rendering I just completed:

And later on tonight I’ll be posting a review of my progress in the 8th week of working through the Empire Building Kit.

Stay tuned!

A Design a Day – Day 266 (What Lies Ahead…)

It’s beginning to hit me that the great beyond is now almost upon me.  My last day at the Milwaukee Symphony for this season (and at least for a full year since I’ll be leave) is on Sunday.  With that comes the end of the “gravy” train – the steady two-week pay check.  Tonight I found myself feeling increasingly depressed and anxious about this fact during the Pops concert we played.  But miraculously when the concert ended and I “escaped” into the steamy night air, my mood lifted immediately.

Worrying about something when you can’t do anything about it (i.e. when you are in the middle of playing Battle Hymn to the Republic) is a recipe for stress, if not for missed notes.  Focusing on what you want to do and taking little steps towards your goals is the remedy.

Some of the little steps I’ll be taking in the coming week involve buckling down to learn an illustrator program, as well as going back to studying CAD (computer aided design).  I’m also going to be posting a bunch of my latest pieces – beautiful professional photos along with photos of the jewelry on my lovely model, Ann.

Here is a modest earring for tonight (another little step…):

A Design a Day – Day 214 (With some thoughts on juggling and other risk taking)

…and exhausted.

I learned an important lesson some years ago when my brother-in-law taught me to juggle.  The hardest part of juggling, much harder than trying to catch the balls, was actually letting them go.  Until I stopped clutching the balls, I made no progress.  When I finally gave up trying so hard and starting letting go, I learned to juggle.  Even better, the higher I let the balls fly, the more time I had to watch them and gauge where they were going to come down so that I could keep juggling them.

My life of late has seen more a pattern of clutching than anything else.  Perhaps that is why I discovered not one, but TWO gray hairs earlier this year.

(I plucked them out promptly…)

While I’m not really thinking of joining the circus next year, I might take up juggling,

and letting go again.

What are you going to let go of today?

A Design a Day – Day 205

Today’s design is one I did for one of my most faithful and supportive clients.    Glenda is a colleague and friend at the Milwaukee Symphony.  She was also one of the first people to commission me to make something for her when I was just starting out in business.  She has been a faithful repeat customer, so when she approached me with a cuff link project for her husband’s birthday, I was more than happy to be involved.

Glenda and Gary (both terrific musicians) own and run Greenhoe Trombones, a premier manufacturer of trombones and trombone components.  To celebrate Gary’s birthday, Glenda wanted me to design 14K yellow gold cuff links around their company’s logo.  The elegant double-G logo is perfect just as it is, so I came up with the following rough CAD rendering to convey my idea for the cuff link tops:

Upon discussion of the type of cuff link backs, overall sizing and receiving Glenda’s approval, the final CAD was reached:

CAD Final Rendering for Logo Cuff Links

The finished cuff links came out beautifully!  And, for my reader’s benefit, I tried to photograph them in exactly the same position as the CAD rendering:

The cuff links are high polished with a recessed bead-blasted finish…

golden treasures for a golden couple!
