There is no weight or recommended needle size for this. The yardage suggests a fingering weight, but I swatched with several needle sizes from 3 -7 and US 6 seemed to give the best result. This yarn will “pool”, stacking thick on thick and thin on thin, so it’s best to swatch to find a good balance. It will produce an interesting lacy looking fabric with the right stitch count and needle size. It doesn’t stand up well to repeated frogging. The thick parts tend to get quite loose. Frogging should be done with care and patience to avoid damage.
