My JoAnn's has a bulletin board with a bunch of contacts on it for people who do sewing/alterations. I have used it several times.I bought a zipper to repair my hunting vest at a fabric store called Jo Ann's fabrics. I asked for help and she told me they could sew it in. I would think they could sew in your pad.
forgot about that.Phil Kiner developed an innovative and cost effective way to reduce felt recoil. The item is available in the womens personal hygiene department at your local grocery store and is called a panty liner. Installation is simple, adjustable and discrete. It can be painful too if you put the sticky side against your chest.
I astonished my present wife the first time we went to a registered shoot together down in Florida. She had a distraught look on her face and said we need to find a store. I said what's wrong and she told me. I said hold on, I'll be right back. The look on her face when I handed her one will be forever etched in my memory.Phil Kiner had a great idea/suggestion. I'll let him come on and tell you guys about it.
