I didn't know you were supposed to reduce liquids for crockpot recipes - I just stopped trying those kinds of recipes because they failed. Maybe I will retry some of them again. Thanks for the tip! :)
It is ideal to have an extra crockpot that is used just for this craft purpose.
Melt Bees Wax in a crockpot, and dip newspaper clippings, pages from an old book or a music score into it to preserve them for saving, scrapbooking or craft projects.
Use a tweezers or two, depending on the size...
