thank you, i bought some 2 inch velcro the idea is two strips on the inside and provide two strips to be attatched to whatever clothing is being worn as a body suit. if it runs from front of chest then over to the top of the shoulder it should be very secure.
the Dredd ones are held on with just Velcro
the pterodactyl will have a strip of snap fastners fixed along the spine
got stuck on the cape, i got to the mark 5 cape then lost heart either wrong shape or wrong material (not good with material) and ended up working on other projects. but i will return to it once i get some more fabric experiance
