You need 2 yards of coordinating fabric, 1 in each print. I like to use flannel or fleece so they are nice and soft against baby's skin.
Press the fabric and then pin them together right sides facing each other. Sew with 1/4 inch seam allowance on all 4 sides, leaving a 6 inch gap on the last side. Turn right side out through the gap you left, then turn the open edges in (you can press the fold in to help it to stay) and then top stitch to close with a coordinating thread, continuing the stitch all the way around. Done and done.
I like to use a zigzag stitch to make it a little more visually interesting. This top stitch also helps the layers to not shift around when washed.
These blankets are great for swaddling since they are so big but not too bulky, and they can be used as baby grows..
They can be rolled up and thrown in a diaper bag as a just-in-case-it-gets-cold blanket, spread out on the grass as a play mat and maybe even turn out to be the famed balankey that the child still favors when they are
Easy Peasy, right?
These are all examples of blankets I've made in the past few months- the monkeys were for my cousin Annette and her baby boy, Alex. The orange medallions with the tan backing was for my sister-in-law, Paige and her baby girl, Hadley. The birdies with the yellow backing were for my friend Karen and her baby girl who is due on 11/11/11.
