For the wings I used a different approach. I bought a few really cheap sleeping mats, sometimes called fitness mat, and sew them between 2 layers of cloth and made an envelope with a flap as well. The flap is held closed with velcro (hoo&loop) which I glued on with special cloth-glue. It holds well and the wings are very well protected. It was a lot of work but I made them for all my better airplanes. Good job. I really like it when someone takes good care of beautifull airplanes.
Thanks for watching. Until a few years ago, there was a specialty store in Japan that manufactured and sold model airplane suits. However, many people make it because they can make it cheaper than buying it. However, cloth is the mainstream material in Japan because it is easier to obtain and manufacture.
