That's a great idea -- I've been diluting the glue slightly so that when I used the paintbrush it spread easier. Using a mini roller would be even easier and very spreadable if dipping from the mini paint container that goes with the roller. My hands hurt from squeezing the glue bottle, which is why I started opening the bottle, pouring it in a container & thinning slightly with water. Works very well and my hands don't hurt anymore. LOVE the roller idea -- thanks!!
