A Few Of My Tips:
I usually put aluminum foil around the edges to keep them from getting too brown and dry. I tear a strip like so then fold it in half.
It took four strips to surround the entire pie.
This does work and it works better than the pre-coiled foil sold in stores. I have found them to be loose fitting.
I purchased this dk wool yarn about three years ago. I think it's from Joann Fabric. I'm looking at scarf and shawl patterns to suit the color and texture. It's really pretty, very soft. -- When I find out which yarn it is and what pattern I'm going to use I will let everyone know.
