After completing Jennifer Moore’s Double Rainbow workshop in March, I was inspired to weave her Full Spectrum shawl.   She had an example at the workshop and it positively glowed.   It is a two-block doubleweave in 10/2 perle cotton that rotates the 20 Tubular Spectrum colors in both warp and weft.   The colors rotate through the warp with 4 colors in each 1” block, using her double rainbow technique in which each time you change the block, you drop the first color and add a new one.   I slightly modified the treadling blocks but otherwise followed Jennifer’s pattern which I purchased from Lunatic Fringe.   The outcome is stunning, and is one of the most beautiful pieces I’ve seen using the Tubular Spectrum yarns.
