Lace Coasters or Mini Doilies

I'm really enjoying crocheting with thread right now. I've made several big doilies, and my most recent project is this set of lace coasters. 

Each coaster is only five inches across. It can be used as a miniature doily or a bookmark. 

I used size ten crochet cotton thread (Aunt Lydia) and a steel hook size 1.5 mm. 

The pattern is available in my Etsy, Craftsy, and Ravelry shops.
