I've just taken the denting exercise from Season 3 Episode 1 off the loom.
I hem stitched each section in groups of 6 (so two stitches per 1/2 inch stripe) and have
been experimenting with a twisted fringe. This is where I am having trouble.

I have a slight tremor in my hands and between that and my fat fingers I am finding it almost
impossible to tie a knot in the end of the group after they are twisted.

So my question is this: can I reasonably leave these 2/16 cotton groups untwisted? If so, would
I be better off to trim the fringe shorter than the current 4"?

I don't suspect that these are going to get a lot of washing.

Hummmm - what you might try is to reinforce your hemstitching with a small zig-zag machine stitch. Try to get a colour that matches the colour of the thread you used for your hemstitich. Another way would be to whip stitch the hemstitch by hand to secure it. It's important to secure the cramming and denting sections of your piece. No one will even see what what you've done unless they look at it with the bifocals ;-)
