I too stopped swapping ages ago because of the "crap" I was getting in return. After doing a bunch of swaps the only one that I received very good things in return was one where the host was very specific (more than one layer, good quality cardstock, one embellishment and a note to "do your best work").
But all the others were bad - really bad. Poor stamping quality, real cheap cardstock. Some where the image was just stamp haphazardly onto paper and not even colored in. I gave up on the swaps and have been much happier!!
