I worked with Beth, aka MissBlackPepper at Etsy, to make a repeating border print design that meets the specifications of the Spoonflower system. I probably could have struggled through the design process in Photoshop by myself, but it was much easier and faster to work with Beth.
Through e-mail and Etsy conversations, I explained what I wanted, keeping in mind that the less mind-reading Beth had to do, the faster the process would go. I requested that the pieces be made up of 1/2" blocks, with some empty black space at the top, an increasingly heavy distribution of falling pieces toward the bottom, and about 6" of stacked blocks along the bottom edge. Of course, the stacked blocks at the bottom couldn't be completely solid, otherwise the lines would clear! (Yes, I'm a big dork. I know.) Beth had recommendations about what colors would print best on the Spoonflower system and how wide the repeat could be before the file size got too big for Spoonflower to handle. I'm glad one of us knew what she was doing!
Beth and I corresponded back and forth a few times as the design progressed.
I ordered three yards of my dream fabric. Two weeks later, my fabric arrived. At $18/yd it's way more expensive than my usual fabrics, but it's so worth it to have exactly what I have been searching for!
Ok, so the black is a little grayish and there are a few very subtle streaks in some of the stronger colors. I don't care. I'm thrilled. Once I decide what to make, I will wear this fabric until it fades and falls apart! And then I'll have more printed and make something new, because I can!
And finally, I think the world needs Tetris-style fabric. If you are interested in having Spoonflower print some for your own personal, non-commercial use (and you promise not to do anything that would result in a copyright problem), e-mail me and I'll share the Spoonflower-ready file with you. Seriously. For free. Really!
