Here's a coin purse I whipped up this morning. If I hadn't been attempting to multi-task, this would have taken maybe 30-minutes to complete. These are just about as close to instant gratification sewing as you can get!
I make these using the Size 1 Card Wallet pattern pieces printed at 85%. If you're printing out your pattern pieces at different sizes, don't forget to mark them! You don't want to get the different sizes mixed up or you might be in for an unpleasant surprise later when you cut mismatched fabric pieces.
