This has images from Doctor Who, Star Trek, Hitchhiker's Guide to the Galaxy, Star Wars, and more that, I'm sad to admit, I can't identify. I bet Zach can, though! I ordered two "fat quarters", one for the front and one for the back of the stocking. I got some plain green fabric for the lining and used some red micro-fleece leftover from a long-ago project for the cuff.
I found various instructions online, but none had a pattern, so I traced my stocking, then made it an extra inch around all sides and about four inches taller. Initially, I drew the pattern on old newspaper, but that wasn't big enough for the expansions I wanted to do, so I used that pattern to trace onto part of a cardboard box. I used that to trace onto all the fabric. I also traced out some interfacing I found in my fabric drawer, to give the whole thing a little more substance, though after the fact, it probably wasn't really necessary.
Next came the tricky part -- adding the cuff. I found this DIY tutorial that had a little more info on sewing the cuff, but it still wasn't super descriptive. I think I did this part three times. Then I decided it would be best to sew the hanger loop inside the cuff, so I had to pull out part of it a fourth time. I started by cutting my fabric twice as wide as I wanted the cuff to be and a little more than twice as long as the stocking was wide. Then I folded it in half, with the good side out, and fit it around the stocking. This was kind of tricky due to the seams in the stocking. I just did the best I could. Then I sewed the cuff to the stocking. When I got to the side where the hanger loop would go, I stuck that in to sew it between the stocking and the cuff. I know that's not very good description of the process, but it's the best I can do from memory at this point.
Finally, I had a finished stocking! Zach thought it was cool; however he couldn't identify all the symbols, so I'm not sure he should be allowed to keep it :-p He liked that it's bigger than his old stocking, though he thinks that now he gets to have both. I told him one stocking full of candy is enough!
