My kids want to be Hiccup & Astrid (from How to Train your Dragon) for Halloween this year... I've looked online and ebay and they are either really expensive or won't ship to Canada!!

Help! I can't sew... so I'm thinking more along the lines of glue gun type assemble? As long as it will last for Halloween! Any ideas? I've never made a costume... where do I start?!? Where do I get the materials from?

Alternatively, if there is a mom who is creative and loves to sew... I'd be happy to pay for your time... it would probably turn out better!
