I've seen so many hoodies out there with fur, but they are either made for kids or VERY expensive. This simplifies things, using a large stuffed bear from the thrift store and some scrap fabric as the lining.
Step 1: First Step: Pattern Time
You'll need a pattern. Either you can buy one, copy one from a hat, or try yourself at pattern drafting.
You can buy my pattern here:
If you copy a hat, be sure to find one with darts at the top for putting the ears in.
Also, there is a pocket where the paws are, a U shaped pattern would do the trick.
The long scarf like parts of the hat, if you are not buying the pattern, also need to be drafted. I'll have to leave this solely up to you because every hat pattern is different.
Step 2: Gather Up Your Supplies
Wash your fur fabric or stuffed animal and set it out to dry. Brush the edges so the excess fur does not make a huge mess.
Figure out what lining you would like to use
Step 3: Mark Out the Pattern
Use whatever marking object you would like. I tend to use pen when I know the lines will not be seen.
Step 4: Mark the Names and Cut the Pieces.
Cut out leaving at least a 1/8 inch seam allowance.
When I marked my parts out on the teddy, I had many parts which almost touched. Make sure to lay out your pieces and find the best possible layout before cutting or marking.
Step 5: Sew Sew Sew!
Match up the parts, which you named and marked so you would not be confused during this step (right?...RIGHT?).
Cut off teddy's ears, and using some of his stuffing, shove it in until they look good and add them to the hat. I had to hand stitch the ears in because my little sewing machine just would not sew through that many thick layers.
Step 6: Add the Lining
Right sides together, sew all the way around leaving a 4-5 inch gap at the back part of the hat to turn right side out.
Flip and iron it. Be careful, and always check on a small scrap of fabric to make sure the iron is not too hot.
Step 7: You're Done!
Yippee! Your hard work has paid off, and you now have the perfect accessory for those cold winter days. Bravo.
