I'm also a 505 user, and depending on the size quilt I may get 3 or4 throw size quilts for Project Linus/toddlers out of one can. I also order from Amazon with my free Prime shipping, last time only ordred two cans, it will last me awhile. Still haven't tried the Elmers washable glue basting, even though I've had everything in my Amazon cart to give it a try....somehow I delete it and go back to 505. Why I'm so chicken I don't know.
