um...where is your blog? how do i get to it? i'm not finding you. anywho, the answer to your question about the canvas...it's 24x12. i got mine from my lss for less than $5. they're canvas concepts and they're normally around $25 for a pack of 2. (i got them on clearance). i'm sure you can pick them up at michaels however. and please forgive me for not knowing where to find you!
