Shadow filet rose doily

This doily is a filet crochet rose, done with tr's instead of dc's; in this way I could use what is known as "shadow spaces" to make the leaves. (A shadow space is ch 1, tr, ch 1, while a closed block is 3 tr and an open block is 3 chs...each is bordered by 2 tr, of course.) Wish I could find more shadow-filet patterns; I think they're really neat. Pattern Source: Floral Doilies by Dover Needlework.
