Of course, maybe you don't want any type of tie at all. No worries, you could also simply sew a hook and eye to the collar's edge.
These work up really quickly, and use very little fabric. Might even be a quick, simple gift idea for someone on your holiday list. One other little hint I'll leave you with -- the pattern has a center back seam. The pattern instructions would have you sew the center back seam in the fur, sew the center back seam in the lining fabric, then sew the two pieces together -- leaving an opening along an edge for turning the collar right side out. That would certainly work, however, I find it easier (when hand sewing the small opening closed) to leave an opening in the center back seam of the lining fabric instead. Actually, I only sew about an inch of that seam on either side and leave the rest open. Then, simply sew around the entire edge when you've placed the fur and lining together. That way, your hand stitching is lining fabric to lining fabric -- plus it's hidden underneath the collar. The other way, you'd be stitching faux fur to lining fabric along a more noticeable outer edge.
