Just pick carefully :)
Got up early and started my Rainbow Marriage Equality Scarf.
350 St on the needle take a while to get through...
7 rainbow colors from Knit Picks (some Swish, some Wool of the Andes) and US6.
6 garter ridges in every color, (12 K rows).
Took only one week. Not bad for:
350 st per row.
12 rows every color
7 colors.
29400 stitches!
