I'm currently participating in two Harry Potter swaps through swap-bot. It started as one and split into two. But this just means I get two people to create for! Let me show you what I made. I'll include brief how-to's, but feel free to ask if you want more detail.
My first partner claims to be a Ravenclaw, so I made her lots of Ravenclaw goodies. Here they are together.
First, I made a Luna Lovegood inspired necklace. Instead of radish earrings, I went the necklace route in case my partner didn't have pierced ears. I just put a crochet bead together with a metal flower using a head pin and hung them from a chain.
Next is a Ravenclaw scarf. I actually had these two scarves that I bought awhile back at the dollar store. I thought they would come in handy for a scarf project. Guess what, they did. All I did was sew them together along the two edges.
Finally, a button set that I made with my button maker. I just found some graphics online to make the Ravenclaw and Hogwarts crest.
For my second partner, I made more general HP crafts, but did include a Slytherin goodie since that was the house she would choose.
She mentioned that she loved tea, so I made her a "Muggle" teacup. To be honest, I was worried calling a Slytherin "muggle," but hopefully it will be okay :) I just found a teacup from a thrift store and then wrote on it with a porcelain paint pen.
Next, I made a snitch necklace like the one I made for myself awhile back. I still had some wings and I just attached them to a gold bead using an eye pin.
Finally, another pin set. However, this time I included the Slytherin crest.
Whew!! That was a lot of HP crafts. Now I just get to sit and wait to see what I get!
