That I used for a pillow cover:
I charted a pattern adapted from Ouvrages de dames... edited by Jule Trigoulet (see the top design on page 9). A .pdf is available of the chart that I made--I used DMC Cebelia cotton size 10 in ecru, with a 1.4mm steel hook.
I love how it turned out! I had started the crocheted panel to be a curtain, but then tossed it on the bed...next to the pillow that had a cover which was wearing out...
Now I'll look for curtain ideas!
