My doubleweave twill sample turned out really well, so I am going to proceed with making a large blanket. I have chosen all the greens, blues, and purples in my 12/2 cotton yarn collection.

Here are my estimates and calculations for this project:

At the warp board: 2 strands at a time, around the board 24 times total for 3.5 yards. This means that there are 48 threads per color change, and with 6 threads per dent that means that each square of weaving will need 8 dents in the reed.

26”x10 dents per inch = 260 dents available, and since the number needs to be divisible by 8, that means I will use 224 dents, leaving 3.6 inches total to be free, which is 1.8” on each side. One extra dent on the right will be filled with the extra center threads to help space out the center better. I might do the same on the other end, add a few extra to make it space out better on the edges.

224/8 dents total per color change = 28 squares total across when unfolded

224 dents x 6 strands in each dent = 1,344 threads total in the warp

I am warping the reed to weave at 30 epi, but after washing, it comes out to be more like 34 epi. Therefore, with 1344 threads, it will be approximately 40” across (approx 43-44” before washing) I am calculating a 12-14% shrinkage rate. It should be weaving up at 22.5” at the reed.

I had to add more heddles to my loom, about double what I had. I am not taking too much thought while threading the color sections. I just want to leave it up to fate.

May 2013:
The blankets came off the loom and were washed in the washing machine. I took out the 2 extra center seam threads before washing it so the threads would have a little room to move. It turned out to be an awesome way of doing it! I am so happy with these blankets! They are about 40”x40” and so soft! I love them!! This is definitely something I want to repeat very soon!!
