Sewline Water Soluble Fabric Glue Pen

The Sewline glue pen is the best one on the market. I've used it in making hundreds of hexies, and the glue held wonderfully once I got the hang of how much/little to be using. As you're using the pen, you'll also start to get the swing of things and rotate the pen to be able to keep a crisp "edge" as you go. (It keeps things cleaner rather than just "globbing" glue each time. It also maximizes your glue coverage without wasting.) :)

Portable and useful
