Sorry OP, but I actually find the listing title, photo and description extemely unclear .... it could be easily interpreted as A pair of Baby Booties plus Hat Crochet Pattern 

A buyer could easily think they are getting the booties photographed and a bonus of a hat crotchet pattern.

Your post costs for a piece of paper are very high IMO and could also contribute to buyer confusion.

I think utilsing buyers feedback to improve your listings is invaluable.  When I started selling and got less than favourable feedback I used this to improve my listings and service going forward, and I think it has saved me loads of angst, made for much happier customers and contributed to my relative success in a number of quite competitve ebay markets.
