Hi-
I found this link to a free pattern:
http://sewing.circleofcrafters.com/f...stpattern.html
I think it is a great pattern to start with & hope you find it helpful.
I've used this pattern twice, with a few modifications. Specifically, I lengthened one of the sides so that it wrapped all the way around Lily and fastened on top. I used velcro closures and bias tape for a nice finished look. I also added an appliqu? for decoration, and stitched everything by hand. It was very easy and I am very happy with the finished product. Definitely looking forward to making more!
Good luck!
