Ok dokie 2 questions: 1. Is it hard to do? And 2. Where's the best info on the interwebz for me to use?
place mushroom cap on a peace of foil, cover with cup....... leave set 24hrs. remove cap from foil- observe print left behind..
not really.. they should be clean though.. Take the 2nd cup down from a fresh stack.. Uncoil the foil from a loop , use a part of it that hasnt been exposed to kitchen counter dust..
