This is the ball comparison. Its 650m per ball so I think I probably used the required 350m. The swallowtail which I have just started in the pink colour (raspberry) takes about 400m but I was hoping to make it bigger than the last one, which is pictured below.
The yarn is Fyberspates 100% Mongolian Cashmere :) Yum!
