Where can UHU glue be purchased? What other types of glue(s) are best for building paper models? Right now I'm using Elmer's Gel glue. It's a pale green color and is cheap(!), doesn't run, and doesn't seem to warp the paper if used sparingly. I used Elmer's white glue originally, but found it has too high a water content (which I've "heard" other modelers say). I've been gathering a large collection of cardboard of various thicknesses by cutting up nearly every cardboard box my wife and I use, cereal, pasta, pancake mix, tea, etc., et al, ad nauseum. When I gather my courage to tackle a more complicated model, I believe I'll have an ample supply!
