I'm pretty new to paper crafts but wanted to attempt some DIY elements for our wedding invitations. I was skeptical about such a low priced corner punch but it was one of the best tools we bought for our project! It's actually quite difficult to mess up. I even let my fiance take over punching the rest of the invitations. You just turn it upside down so you can see the paper line up to the notch and you're ready to punch. I'll upload some detailed photos so you can get a better look. They have this removable clip so you can attempt other patterns but I felt it was pretty difficult. I would stick to just corner punches with this tool. It's also much smaller than the other corner punches that I've seen so it'll tuck away quite nicely. Plus, it's about half the price of those other punches. I highly recommend this tool for anyone on a budget or even a first timer.
