We really enjoy following along with American Patchwork & Quilting's 1 Million Pillowcase Challenge! Each quarter, their team creates two new designs and makes up sample pillowcases featuring new fabrics. Here are the two most recent designs:
Tumbler Band Pillowcase
featuring Ro Gregg's Calypso Goldfish collection
Find the free pattern for the tumbler band pillowcase here.
Honeycomb Band Pillowcase
Find the free pattern for the honeycomb band pillowcase here.
You can find these two pillowcase patterns, as well as 39 others, here.
