Velveteen is a tricky fabric to work with but -oh! - so gorgeous. I love it for all sorts of projects: Christmas stockings, crazy patch quilts (above), clothing, purses....the list goes on.
But...it's...tricky....and...finicky. So there are a few rules to working with this wonderful, elegant fabric.
#2 Layout: Besides laying the pieces out in the direction you've chosen, pinning the pattern pieces doesn't work really well because of the thickness of the nap and "nap creep". Nap creep is the two different layers moving against each other almost involuntarily because of all those fibers sticking to the plush surface. The pattern wrinkles and moves as you pin. The solution?: pattern weights. Lots of them. It really does help. If you want to make some check my post here.
#3 Sewing: Yes, you guessed it again....that little devil nap causes problems with creeping seams. My solution is to pin FREQUENTLY at a 90 degree angle to the seamline. This keeps the creep from happening as you stitch the seam. Use very fine pins and keep them in the seam allowance to avoid marking the garment side of the fabric. Always do a sample first on the machine to check stitch length (about 2.5mm is good) and tension. Use an even-feed or roller foot, and slightly loosen tension.
#4 Pressing: Pressing matters....nap can get crushed so steam pressing, not ironing (there is a difference) is best done on a needle board or over a thick bath towel with the nap facing into the board/towel. A needle board can be actual needles , a wire needle board.
Other velvet needle boards are more like the soft side of velcro (not the hook side). I found mine at a thrift store still in it's original packaging.
