I bought this Woodware snowmen stamp with the intention of making acetate cards at card club.
It's quite a long stamp so I thought C5 landscape would be perfect. I sat making the card and then when it was finished ...realised it wouldn't stand up as the acetate wasn't quite thick enough.
Plan B - make the card portrait instead, using part of the stamp instead of the full image.
Eventually I managed to get the original card to stand by adding a couple of strips of card along the bottom edge. I do prefer this version but it was nearly thrown out of the window at one point!
