Hi,
You might want to check with Everything Cross Stitch and see if they carry cross stitch bands. If you click on the title underneath the picture in your chat, you will come to another screen and right below the title it states 16-count stitch band to do the pattern on. ECS is closed on weekends, but if you e-mail them at: sales@everythingcrossstich.com or call them at 1-800-800-8517 on Monday they can probably assist you. They have an EXCELLENT customer service dept. here. Also, Kristi may very well see you "chat" and get back to you on Monday.
I'm not an employee of ECS, but one of the stitchers that saw your "chat" question.
Were you planning of making this into a book marker or a bellpull? It is a nice design and appears to be able to be cross stitched up quickly. :)
