I forget where and how I learned this but after a while, even punches lose their cutting power. While punching out over 1,000 of these little flowers for shower, I noticed over time that it was harder to actually force the punch through cardstock. It was partially my thumb because I started to develop a blister but it was also because the punch was loser it’s punch. haha..
I recalled learning that you can bring your craft punches back to life with parchment paper + tin foil. The tin foil sharpens the punch and the parchment paper waxes the punch so that it’s easier to punch through heavier paper.
