I found a canadian distributor! After a few weeks of searching (Don't even get me started on Michaels, Bouclair & WalMart's customer service...) I finally found out that Fabricland will order the Lustre variety of the iron-on vinyl for me - special order, but still! (yay)
If you want more information, please send me a message, and I'll forward the information I received on to you.
I'm so excited that I'll get to make one of these bags!
