A really effective modern way to use any of those materials is to just coat what will be the insides with Diamond Flex. A flexible UV resin. The biggest advantage of doing this is speed. Coat, zap, cut out, and tie in. Non of the waiting around for adhesives to dry. Another great thing is that it doesn't add any bulk, that makes it easier to tie small.

I've tried the packing tape method, no matter how waterproof the makers claim there tape is it isn't waterproof enough for flies.

At least you have found a use for tea bags, other than making perfectly good water unpalatable.
