if you don't want to order 12 rolls Dubro sells the exact same thing in one roll packages it is $5.00 a roll though. works great by the way for hinges on a foamy. I bought mine from woundcare the 12 roll package 1" wide and pretty much have a lifetime supply now. Second way and not as easy way is to cut CA hinges into thirds. cuts slots and glue in place with thin foam safe CA. You still won't have a sealed hinge gap this way and will still need to seal the hinge gap with tape if desired
