Using leftover scraps of sock yarn -- fingering and sportweight.
Update 1/13/12: I think this project sealed my love for fingering/sport weight stripey garter stitch square (or rectangle). I love it for that and because without it I might never have made Parcheesi as I did.
I never love love loved it -- never enough, in all this time, to even weave in the ends. So, tonight I ripped it. Two hours, start-to-finish. I can put that yarn to good use.
