December's Block of the Month is called Scot's Plaid and comes from the book 501 Rotary-Cut Quilt Blocks. The size of the block when pieced should be 8.5" square to finish at 8" square. Colors for this block are to be warm, earthy tones with a neutral fabric for the large corner piece.
I made two sample blocks in two different warm color schemes.
Sew one 2.5"x4.5" strip to one side of the 4.5" square, and press towards the strip; sew the other 2.5"x4.5" strip to the dark 2.5" square, and press towards the strip; trim if necessary and sew these two sections together as shown above matching seams.
Sew one 2.5"x6.5" strip to the other 2.5" square, and press towards the square.
Sew the other 2.5"x6.5" strip to the top of the block in progress as shown above; press towards the block.
Sew the pieced 2.5"x6.5" strip and 2.5"square to the right side of the block as shown above, matching seams. Trim to 8.5", if necessary.
Stand back and admire your beautiful block! Repeat all steps as many times as you please to improve your chances of winning all the blocks ;-)
