Woodware do a great selection of square punches which all nest together.
The 1" punch which I have used here is yellow.
I have stamped onto white card with black and clear embossed the stamp JGS338 geometric leaves and inked over. Then splattered with thin bleach to give the little white dots. Once dry, I have punched eight squares and inked the edges with a brown ink.
Adding avocado liquid pearls and a greeting to finish it off
using JGS 324 in the frame ditties.
