Kristen asked what brand of gridded block I used on the precise stamping tutorial. It's from Papertrey. I would link to it, but it's been unavailable for over a year, so I'm not sure what happened to PTI's supplier on this, and a quick google search turned up nothing but out-of-stock notices. If anyone knows another source for the same block that is in stock, please link in the comments!
I have a large gridded block from Martha Stewart (bought at Michael's) that is nice, but it's too big and heavy for sentiments. The PTI one is 2.5" x 6", which is a very useful size for aligning things on cards. Perhaps Martha has one in a more appropriate size. Anyone know?
