I used nearly 3 oz. of roving for this. After I got the whole piece nice and wet with soapy water, I worked every little square by hand to firm up the edges and make sure they were nice and straight.
Usually I like to wrap up my scarves in bubble wrap and start rolling them immediately but this was so delicate that I did a lot of the work gently and by hand and only rolled it in bubble wrap for a little bit in the middle of the process.
I am going to keep playing with this style. I would like to add needle felting at the intersections but I plan on wearing it this weekend to the Surface Design Conference in Seattle so I won't have time yet.
