It seemed so simple when someone asked me if I'd make a nap mat for their little one. She wants it 28x54 and we decided on flannels with batting. so, I'm thinking about how to do this, and thought I would just right sides together, sew around 3 3/4 sides, turn and voila. I can do that, easy peasy. But then I was thinking I'd need to stitch the top of the whole thing to hold the pieces together. ... now it's starting to sound like a quilt and I don't want to make a quilt.
So, here's my question. If I make it like I said above, and after it's closed, just make some simple lines of stitches from one side to the other, I'm afraid I'm going to have puckers.
How do I do this without puckers? did anyone follow that?
