You will need:
-A painters canvas (9ft x 12ft)
-Thread/ a sewing machine
-A washer and dryer
Step1: Cut off all edges of painters canvas and cut to desired size
Step 2: Sewing 1 inch in, sew a stich around all edges of the blanket. I did a double stich but whatever you prefer.
Step 3: After sewing around edges, throw in the washing machine and then dry on high to frey the edge.
Step 5: Go have a picnic! Yes it is seriously that easy! And if you are ambitious make a couple of pillows to match, you will have plenty of material left over!
