Tote Bag Handle Problem

Christmas 2009 I went crazy making tote bags (15 in all).  You can see them in my post of December 1, 2009. For many of the bags I purchased vinyl for the handle. I thought it would hold up better and was worth the extra cost. The bags were a hit. Unfortunately, friends and family who have used their bags a lot have found that the vinyl handles have separated. This weekend I've spent my time trying to repair one friend's handles. This has turned out to be much more of a challenge than I expected. FabricTac glue did not hold which was a huge surprise. I finally used Gorilla Glue but even with it I had to use bulldog clips used it dried. I had a moment of panic when one of the clips got glue on it and resisted coming off. Hopefully the glue will hold it together. I was going to make some more bags (only 1-2, the obsession to make many has passed) but will pass on purchasing vinyl handles.
