I'm not expert in rhinestones but you didn't get a reply so here goes.
Are you sure you are giving it long enough to get really hot? Can you get the crystal to stick to anything? Is it only the bows it won't stick to? If it sticks to other things okay then it must be the bow material, otherwise it's the wand or the way you are using it. The girly coloured wand should work okay. The wand is just a glorified soldering iron. I've got one of those and it worked fine (they stuck) although it didn't fit the jewels I had exactly. Is the tip fitted on closely? Are you using the correct size holder for the jewel so it gets lots of contact and gets really hot? Is the glue visibly melting? Melt one to a piece of cloth and smear it. The glue should be visible. If you see this glue then the wand works okay and it is the bow fabric that is not compatible.
Is it beadsandcrystals.co.uk you are using? I see they do a bulk 1440 crystals for £35. Still quite expensive.
Consider making your own bows, putting crystals on them and then retro fitting them to the hats. Bruce.
