I know Sue Daly, lovely lady who did the EPP for years before it got 'popular' - she so deserves her success!!!
I glue my hexies, its quicker than stitching. The Sewline glue pens should be available in the US. I used to use them but you go thru the glue refills so fast and they're not cheap. I now use cheap glue pens from the supermarket without issue. When it comes time to remove the papers you just run a pin along under any stubborn bits. No need to wash, it leaves very little residue and most are totally water soluble anyway. Hope this helps a little, cheers, Pami
