You will need about 1/2 meter each of the lining and shell fabric. The fabrics can be anything that will not be too stiff for the scarf or too uncomfortable to wear around your head and next to your skin. I recommend jersey knit, fleece, fun and faux fur, recycled sweaters, corduroy or flannel. There are many many possibilities. There is no reason why the lining has to be the same or different from the shell - its completely up to you.
The scoodies shown here is of a polyester knit (but not very stretchy) and faux fur:
Cut two hoodie pieces of shell fabric
Cut two hoodie pieces of lining fabric
For the hoodie shape, I highly recommend strolling over to your closet and pull out your favorite hoodie and simply tracing the shape (and adding seam allowances).
Or you can use this general shape:
For a medium adult size, try drawing a square 15" x 12.5" (for a medium child size, try 12" x 10.5") on paper and alter it to make the right shape. These measurements include a 1/2" seam allowance. I recommend here drawing your pattern and cutting two light-weight paper pieces to tape together and try on you head. Once you''ve got your size and shape down, then go cut the precious fabric.
Step 2: Cut scarf pieces.
I have no measurements here because it is entirely personal preference. However, I find piecing together a 9 foot x 4 inch scarf to be nicely wrap-able, dangley, and comfy all at once. This is a very long scarf, though, so use your judgement.
Usually the scarf must be cut in two pieces and joined together at the neck, but you may find more divisions necessary.
Step 3: Sew the hood.
Put 2 shell pieces of hood right sides together and sew the back. Do same for lining. This will give you your hood shape.
Put shell hood and lining hood right sides together and sew up front (face opening. Turn pieces right side out and top-stitch around front to keep everything neat. I also like to stitch the neck to secure the shape.
This is after seams finished, but before turning right sides out:
Step 4: Attach hood to scarf *
(at the bottom of this post is additional instructions on attaching the with spanky illustrations for the visual learners, like me)
With right sides together, sew the hood to one side of your scarf.
Step 5: Sew scarf.
Put right sides of scarf together with the hood sandwiched between and sew seams almost all the way around, leaving a gap about a foot long. Do not sew the seam opposite of where the hood is attached. In fact, you probably will not be able to sew this section because the hood will certainly interfere. This is the part where you will pull out the scarf ends and hood. Before you sew this final part up, double check the hood area for exposed stitches or tucks and such. Last chance to neaten it all up.
Turn scarf right sides out and top-stitch around edges closing up the final open seam.
Step 6: Add embellishments.
Pockets, applique, rhinestones... whatever takes your fancy.
