I buy my spray baste on sale at JoAnns when they have a 50% off coupon. I use Spray-n-Bond which is not found in the quilting area but near the buttons etc. It is for machine basting and embroidery and clearly marked. I have also ordered the same spray on Amazon and it is about half of the regular price at JA. I have also ordered from JA online. I can usually get 3 quilts spray based per can.
