Martha Stewart Border Punch Tip

I was so frustrated with my MS border punches, particularly those with lots of intricate detail like the scallop lace one. It just would not go through my Papertrey cardstock. Turns out because Papertrey cardstock is so much denser, it really does not work well with these punches. I tried a sheet of Georgia Pacific (from Walmart) and the punches will punch that just beautifully.
