I decided to use the Urban Unisex Hoodie from Heidi and Finn . I haven't made one of these yet for my daughter but I made one for my 7 year old nephew for his birthday. I like the pattern because with a quick modification it is fully reversible. I used orange and black fabric on the outside and added furry little pockets and ears on the hoodie. I made a size 4 so my daughter can layer underneath it (Halloween in Canada can sometimes mean winter jackets are needed!)
A Tutu skirt tail! I just tied pieces of tulle to an elastic. The tail I made by braiding together some novelty yarn I had in my knitting stash.
Ruby and Jack: Simple Seaside Shorties and Capris. I made a size 4 and extended the leg length so they would be full length. I made the version with pockets and a ruffle bottom. My daughter will be able to wear these with anything once Halloween is finished.
And onto Pumpkin Boy!! He isn't in his full costume but he found this silk play scarf and was wrapping it around himself so I tied it on like a cape and he loved it. The hat I made for my daughter when she was 6 months old. The next year I added a couple of rows of crochet around the bottom to make it longer so it would still fit. And this year my son gets to wear it. For Halloween he will have on a green fleece outfit that was given to him.
