What a wonderous sight ...
until you look on the other side!
I could have sworn they said this was Donegal when I bought the cones at WEBS last spring, but their website only shows a 2/6 Donegal and this is definitely a single. After winding back to front for the last year or two I decided to wind separate colors and use front to back. Yikes! The singles were wrapping themselves around each other and made quite a mess. But it's only a three yard warp so the tangles will be easy enough to work out. If I decide to use this yarn for a longer warp I will be sure to wind the it in threading order.
Jackie asked if I had done other doubleweave blankets. I have woven 5 or 6. I switched some of my old blog posts over to Movable Type so I could search more easily and I found pictures of a few. My first doubleweave blanket was done following Chandler's suggestions. It was the second thing I ever wove and I used leftover yarn from two sweaters. I thought it was a little tight at the fold so I just pulled two warp threads out.
For my second I tried using fishing line as described in Handwoven's Doubleweave Issue (J/F 2002). That worked well as you can see here and it's what I've used ever since.
