Cosmic Dust Shawl Pattern
The sample used Shirley Brian 100% 4 ply cotton, but it would also work well with Wolle’s Color Changing Cotton (100gr). Another option is to use a fingering weight mini-skein set (best where the total is around 150g and individual skeins are 20g or more).
The sample used ~1300 size 6/0 seed beads (8 color changes in 140g/480yds of yarn).
The number of beads will depend on how many color changes you have as well as the amount of yarn you use.
