I fell in love with this project when I saw it:
I'm not a sewer and wasn't familiar with the term 'jelly roll' but the idea of weaving scraps of fabric cut into strips with a thin cotton warp appealed to me.I'm not one for following patterns to the letter. I used the heddle that seemed most suitable which I think is an 8-dent. My rigid-heddle loom is the smaller (12") width. These pictures show the warping and the cotton.
I had to learn to hemstitch and I'm glad I have that skill under my belt now.
I wasn't particular about cutting the strips of fabric. The pattern gives 5/8" as the width of the 'jelly roll' strips, so I tried to bear that in mind but in reality it varied a bit. Of course it was going to roll so I didn't think a rough edge would matter, and it didn't.
I enjoyed the weaving very much. My selvedges became neater and the pull-in became less as I got through the four placemats that I'd planned. When I lost track of whether the heddle should be up or down, it was soon obvious, as you can see in the picture above, and was easy to backtrack.
The palette and pattern in the skirt played out nicely in the weaving. Most of the time it was compliant and rolled nicely so you see the right side of the material whichever way up the mat is.
More by luck than judgement, both the warp and the weft lasted almost exactly for the four mats, which 13.5", a size I decided on when the first one looked about right.
Here they are finished and in use.
