About an eon ago, Sharon asked about Peg's idea for measuring the length of a project on the loom. Well, by now I'm sure she's figured it out for herself, but for the record, I've been using this method for measuring my dishtowels and have found it to be the best thing I've tried so far (and I've tried a lot of things.)
When I first bought the tape, I got to WalMart and only remembered the "tape" part, so I purchased bias tape. This proved to be too bulky, and when Peg reminded me that she actually said "twill tape," I got some of that on my next trip to the store. My choices were 1/4 inch or 3/4 inch, so I opted for the 3/4.
For this project I simply put two marks on the tape, one to mark the point where I want to begin measuring, and one at 30 inches, which is the on-loom length that I'm currently weaving. It would be easy to add additional marks if I wanted to place border designs or note the center of the dishtowel.
Permanent marker tended to bleed into the tape, so I'd probably use ball point pen next time.
The bias tape is only two yards long, so I'm reusing it for each dishtowel. I pin it with t-pins at the beginning ......
...... and then when I get to the second mark......
....... I stop. Then I weave enough space in between towels to sew and cut, re-pin the measuring tape at the starting mark, and begin again. I'm not letting the tape wind onto the cloth beam, but simply moving the pins as I advance the warp.
So far it's working very well and my dishtowels have been all the same length. Yay!
Oh, and one more tip. No matter how much your cats try to convince you that you need their help.........
Please note that twill tape in not, I repeat not, cat proof.
