I had fun making these out of the "Oh Cherry Oh" Jelly Roll I won in the Moda FabricMatcher contest for the month of December.
I used the chain-sewing technique to make the sewing of these segments go quickly. I didn't even cut them apart after sewing on one side...I just flipped them over and began chain-sewing the other side.
Press the four-patch blocks open, and you will have 36 four-patch blocks. Use 9 four-patch blocks for each placemat. Sew into three rows, and then sew your rows together.
Attach your binding and your placemats are done! A Jelly Roll with 40 strips will make 12 placemats...I can't wait to make some 4th of July, Halloween, Thanksgiving and Christmas placemats for myself and for gifts!
