Step 1: What You Will Need:
Fabric. I used two contrasting colours of velvet because I didn't have enough of the green for the tail as well. I did have to be extra careful when cutting out because of the nap. Fleece would work just as well.
Interfacing. I think I used around 1 metre for an adult sized costume. This stabilized the velvet and made it stiffer so the spikes stood on their own.
Stuffing, enough to fill the tail.
Onesie (I bought one to save time but feel free to make one if you have a pattern lying around)
Paper scissors for cutting out the interfacing because I didn't want the glue on it to mess up my fabric scissors
Fabric scissors for cutting out the velvet.
Triangle templates for the tail and the spikes. Don't forget to add seam allowances.
Step 2: Cut Out Triangles
- 2 velvet
- 2 interfacing
6 triangles are needed for the tail
- 3 velvet
- 3 interfacing
(I tried four triangles for the tail, but ended up unpicking one of them because 3 looked a lot better)
I cut out 54 triangles in total!
Step 3: Sew the Triangles Together
When all of the little bundles are all pinned and ready sew 2 sides of them (leaving the other so you can turn them the right side out) and clip near the point, so you do get a point when you turn them right side out.
For the tail triangles you want to sew both sides of the middle triangle right sides together to the other 2 triangles so you end up with a very wide triangle (see pic above).
Step 4: The Tail
Stuff the tail until full. Do a running stitch around the edge of the opening and pull to gather. This gets rid of the raw edges. Pin the tail to the onesie (Make sure it's placed high enough that you can sit down in it!)
