What fabric do you use for hooking... and where do you find it?
I recommend using wool... 100% wool is best, but I have used an 80%/20% wool blend because it was the EXACT color that I needed for my project. Plus, 100% wool dyes beautifully and will last so that you can pass your hooked piece down to your kids and grandkids.
Skirt or pant weight wool works best, but I've used a lot of coat weight that I cut into more narrow strips. There are a few wools that you probably want to stay away from because they ravel badly... wool gabardine or loosely woven plaids or tweeds are not good choices. However, if you can find a tightly woven plaid or tweed, GRAB it. They can add a "textured" look very nicely.
Using new wool can be very expensive... up to $30 a yard. I suggest that you get in the habit of making frequent trips to the Salvation Army and thrift stores in your area. Garage sales are also a good source, IF you live in a colder climate where wool is worn on a regular basis.
We're in Arkansas and it doesn't normally get THAT cold and stay cold. As a result, wool is hard to come by at garage sales, but I do find it regularly at the Salvation Army store. Look for the larger pant and skirt sizes... you get more wool for your money.
I have a friend who sews for the public and also does alterations and she saves her wool scraps for me. Tell your friends and relatives that you NEED their wool clothes when they start to get rid of them.
Remember, that you can dye the wool to whatever color you need. So even if the piece is ugly and a hideous color... get it anyway and dye it!
A word of caution... sport coats and blazers normally have a lot of iron-on interfacing in them. If they do, DO NOT use that part, even if you pull the interfacing off. Some of the glue residue stays on the wool and makes it hard to work with. As a general rule, I pass on sport coats.
We offer an excellent selection of both new and "recycled" wool.
