Mr. Harris had hit the hap'nny nail squarely on its crown. Forget hide glue - it stinks to high heavens, is a nightmare to get to original consistency unless hermetically sealed and temperature-controlled stored. Elmer's white glue is OK but too runny to suit me. The best stuff I've found yet is Alene's Tacky Glue, sold in nearly all first-line fabric stores and most chain specialty arts & craft stores like Total Crafts, Frames for You, U-be Frames, etc., you get the idea. Comes in small (4-oz.) burnt-orange colored tubes with a white needle-nose spout top. It has perfect consistency to work over time; stays gummy but won't run unless you over-apply, very easy to clean up and actuallly does DRY CLEAR, which a lot of that stuff so-advertized does not. Only consideration is that it is water soluble, so think about what application you are going for (e.g, exterior components to a gunslip, etc.). Don't even go near synthetics - they are like dealing with roofing cement. If you make a mistake on a wooden case lining and try to take the fabric up, those things will actually lift the wood fibers! Worst job I ever took on was - I swear - a Loius Vuitton trunk case for a SxS Greener Empire 12 ga. I actually had to use a wire cone brush on a power drill to claw out the old pukey-green lining which had been glued down with synthetics. I've done a lot of them but that was the worst! KBM
