But with all that black warp and weft yarn, a cloud can make things difficult...
There could be a lamp or some track lighting above the loom, but the small LED tape was a tempting answer to putting the light right above the work. They came from Inspired LED at http://www.inspiredled.com/. The tape comes in a roll and is only about 1/4" wide. I just couldn't bring myself to glue the tape directly to the maple of the loom. Then, it came to me to glue to one of the spacer sticks.
The final question is how is it on the loom - see for yourself!
The coolest bonus is I can move the light between looms....
