Spoonflower
Oh. My. God. I’d heard of Spoonflower before but, as I wasn’t really a sewer, I hadn’t had much cause to visit. I just checked it out again. You guys, it’s basically Threadless for fabric! You can upload your own design and get it printed, and you can also buy designs that other people have uploaded to sell. They’re having a contest at the moment to pick a favorite robot fabric. ROBOT FABRIC. Excuse me while I just go “Squeeee!” in the corner. (I could have a robot skirt. ROBOT SKIRT! ROBOT SKIRT!)
Edited to add: Seamstresses! Which fabric do I need for a skirt? Will the quilting cotton work? Will it be too thin?
