So it turns out I'm a complete TWIT when it came to the sewing machine, I had the whole thing rigged up fine and all my threading was done properly, I just didn't know to put a little lever down to make the stitching actually happen. Oops! What a complete muppet... Mum sorted the problem within about 2 secs of me getting there! My tension was a little bit off too! he he he... so watch this space, I'll have stitching on my cards soon!
