I haven't done mine yet, so no suggestions on the type of paper. I just bought my corner cutter and perforator this weekend. I bought the cutterpede paper cutter, which has an addition you can use to perforate. The corner cutter I bought is just like a shape puncher (if I remmber right, I bought ALOT of stuff). I don't have a picture, but if you go to Michael's again, all of that should be in the aisle together with the whole punchers that have shapes (flowers, circles, etc).
When I went to Michael's for this a few weeks ago, they didn't ahve ANYTHING, then this weekend a whole aisle, so perhaps they are updating their merchandise....
