Sorry UglyCook - it was Brendadawg that mentioned not sewing over stitching - on page 4 - that had me confused with the picture of your jacket.
I'm a newer than new quilter and am just such a scaredy cat when it comes to trying something new but I keep telling myself - what have I got to loose besides an old sweatshirt - LOL!
I'm going to get brave and try it SOON. I wish a lot of these people would share some of thier pictures of jackets they've done.
