I have been to Michael's and Joann's to look for chipboard and can't locate it. Is it in the scrapbooking section? Also will there already be 5 by 7 pieces or will I need to cut it myself? I will try AC Moore today,
Try hobby lobby they have it! If you just need 8x8 then look in the scrapbooking section with the Zutter stuff. If you need another size go to the back of the store in the framing dept. You can buy a piece of mat board in any thickness you want for less than $2. If you ask the framing department may even cut it for you to the size you need. Hope this helps.
Thanks for the replies. I am a little impatient and didn't want to wait for Amazon. I ended up just using 4 pieces of the cardstock glued together and then laminated for the cover and back. It seems sturdy enough. I would have just ordered it but I really wanted to get the book done while I am on vacation and get started on some T-shirts.
