I received a free sample from Maria Filosa's UHU project blog. The sample that I received was a tube of craft glue for foam rubber and flexible materials. I brought some foam products from Michaels and made something for my sons doorknob. I was quite pleased with the results. Although I would not recommend that small children use this product though. The adhesive is very sticky and has a faint adhesive smell. I'm sure that I won't have to worry about any of my embellishments falling off of my project.
