One really easy way to celebrate changing interests is with quick and easy pillowcases. We can change them easily as the kids get interested in planes, trains, boats or characters, and later I might turn them into a memory quilt. (Insert mommy blubbering and growing up fast remarks here!)
I can frequently find fabric on sale or with a coupon, too. Right now, jet planes are the thing.
What you need (fits a standard bed pillow with narrow hem)
3/4 yard fabric & coordinating thread
Instructions: (Make sure fabric cuts are straight and square for a better finish). Fold the fabric right sides together matching selvedge edges. Sew along selvedge edge and one adjacent edge using 1/2 to 5/8 inch seam allowance. Add a narrow hem on the remaining open edge. I folded 1/4 inch twice and stitched to make the hem.
All done! Happy sewing.
