So the pictures suck. There's just no good way to take them. So I'll explain it the best I can.
- 1/2" elastic band bought off Amazon. Cost like 8 dollars for about 10 feet I believe.
- the top flap, elastic, and pleat are all sewn together. I didn't need it to open that much so I did that to being it down a size.
- the bottom flap and the elastic are sewn together but not attached to the pleat so that it allows it to open all the way like before.
- the elastic in the back is 1.25" long and as you work around the saddle to the sides the bands get slightly shorter with the shortest being 1" to keep the contour design of the saddle.
Hope this answers your questions. I just took mine to a sew shop and told them what I wanted and they made it happen.
