I like the Dritz one and tried a Uhu stick. Both of them say "washable" and I think that is key. When you think about it - most people use glue sticks TO STICK things together that are supposed to STAY TOGETHER. lol Leave it to us quilters to want the "oh - but I only want it to stay until I don't want it to stay anymore" type. LOL.
BTW: I got upset about the amount of glue that was still in the tube when the pushy-thingy wouldn't extend any further. So I used a semi-stiff little brush to transfer the rest of the glue. Those sticks ain't cheap - gotta get it all!
