I prefer to use this printing of the pattern because the purchase of this leaflet also give instructions/“recipe” for the child and adult versions.

I also found free and non-copyrighted garter stitch booties and a garter stitch hat pattern online to match the jacket. I don’t have the links to those patterns but I do have copies. Send me a message and I would be happy to forward them if you’d like to knit this as a “set”
