She said that I stretched the fabric when I sewed it. I don't remember doing that, but as I've said before, I am still in the learning process. I've taken a couple pictures, I'll post some tonight to show you what happened.
See, when I picked it up she said "because you stretched the fabric on the back, the green fabric "puckered"." I thought it was no big deal 'cause I like the puckered look. But when I got home and saw it, it wasn't what I would call puckering, there were areas where it looked like she folded it and then sewed it, ya know! It's not all over the back, but enough to where it stands out.
