Like I said, the back isn't great. One day I will have to make the contoured waistband. See the belt wrinkle? That's because there is a sharp V in the back of my pants that the belt can't follow. See the really wrinkly things??
I've found the perfect topstitching guide feet by the way. I use a 3/8" and 1/8" for the topstitching. It gives the perfect space between the rows of stitches. I get my feet here and I love them. I have 1/32", 1/8", 1/4", 3/8", and 1/2". I've ordered from this eBay seller several times and they always ship fast!
