More information on Laying Tools:
The Gilded Edge has a marvelous tutorial on laying flat silks w/Tekobari. I really liked this site & the photographs above & below the frame demonstrate the use of any laying tool! (and, if you wanted to know how to use Koma -- check HERE)
I tried to take some photos - but mine were not great [lighting issue]. So, went on-line & found wonderful tutorials. Link Here for another site with laying tool tutorial. PLUS, they have a section of Free Samples loaded with complimentary patterns. There is one by Laura J. Perin which (IMO) would be great to practice with a laying tool - has loads of straight stitches / satin stitches.
Another excellent LINK HERE demonstrating the use of laying tool. The pictures are wonderful!
OK, I realize now, that I didn't get the link in my last post for Glass Laying Tool. They are quite beautiful. I have never held one in my hand!!
FINAL TIP: Don't forget the Thread Heaven. IMO - helps tame the fibers and keep them tangle free.
