my favorite is a round rotating cutting board from Come Quilt with Me
the obvious: rotary cutters in 3 different sizes, small cutting board, large cutting board 36" wide, dillybob, seam ripper etc
I don't make templates, have them made by a local glass company, about a buck each - have 50+ that I've acquired over time, use and love.
many clear plastic scrapbooking square boxes in which I keep the 12-15 projects in the works
Nancy Crow's 3 1/2" x 12" ruler
a 2 1/2" X 6 1/2" ruler
paper towel and toilet paper cardboard cores on which I roll cut strips
there's npthing I can think of for a wishlist
I usually buy notions at large quilt shows because the vendors have the latest items from recent market shows
