t4t,
If ya wanna use it for patchin, try looking at 100% cotton denim(like bluejeans). It might feel funny walkin in a fabric shop with a micrometer the first tyme,all them wimen folk an such, but it get's easyer! I found a nice .021 that crushes too .013 works great in the .54!
Look at the top of the Bolt for fabric content,but don't be fooled. Some 100% cotton has what they call "guide fibers" that are poly. Find a cut edge and pull a few fibers,if they'er there you'll see'm.
If the stuff is $8 per yard ya can get a 1/4 yard fer $2,,,that's 9" wide and 36" long,,,plenty fer experimentin.
I've found the biggest selection of thickness is in denim,don't forget to wash and fully heat dry the "sizeing" out afore shootin. :grin:
