I have done both glue methods and have at times had problems with when they dry they shrivel and have non rounded tops and other times they were perfect.

any ideas on this maybe i need to dilute it more or i dilute it too much? I figure i need to just be more careful on my dilution measurements. I use elmers glue and dilute it about 25% with water giving me a 25:75 ratio now most of the times i just guess and i eventually get it right but am curious why i seem to get a lot of rivets i have to replace because of the crinkled heads.

A couple times I went to extremes and bought w bazillion pins cut the stems short added a little glue and pushed them into the surface. needless to say this took forever but the results were stunning.
