Jenny Garland Nap Mat Tutorial...You can order the foam from Walmart.com and it is enough for 2 mats. I also found it was easier to have the bottom velcro instead of down the one side. My boys LOVE their nap mats though!
Cuddle up to nap mats with built-in pillows, great for day care and play dates. Bear, owl and lion mats close with hugging elasticized arms and comfort pillow mat clips closed with shoulder straps. Mat rolls up and has shoulder straps for easy travel. DIY with Simplicity Sewing Pattern 1389.
