I prefer 505 to other brands of basting spray, and it's difficult to find in my area (although I can find other brands at Walmart, JoAnn's, etc.). So last time I ordered from this website:
http://www.sewforless.com/item/505_T...OUND_ONLY/7391
It's worth the shipping to get a couple of cans of this at a time.
Be aware that there are 2 different sizes of 505. The one at the link is the large size can -- will do probably 3 queen size quilts. The only difference between the yellow can and the red can is that the red can is manufactured in Europe; contents are the same.
