Draw something to represent blessing on the matt side of the shrink plastic sheet.
You might want to read the blessing in Numbers 6:24-26 or in Deuteronomy 28:1-14 to inspire your pictures and words. Remember that writing needs to be mirror writing and that your design will shrink to 40% of its original size.
Cut out and make a hole, remembering that the hole also shrinks.
Shrink the design at 170°C in a household oven.
Attach your design to a keyring to keep or give away as a way to remember God’s blessing on you.
