I can think of several cross stitch patterns that could be enlarged and used for a pillow design. Cartoon characters with simple line art like those pictured would probably be best. Winne the Pooh, Hello Kitty, etc.
y around the strip starting and ending in one corner. Then to create the loops to go around the curtain rod, I chained ten up from that corner, skipped 4 stitches and single crocheted one, chained ten, skipped sc on.
