The votes are in!
As of the time of this post - button C is the landslide winner!
I sewed the winning buttons on and now I have a finished Liesl:
Pattern: Liesl by Ysolda Teague
Yarn: Debbie Bliss Alpaca Silk - 10 balls or 700 yards
Size: Between L XL
Needles: Size US 11
Alterations: I think I actually knit between a L and an XL as I just knit until the sweater fit over my shoulders. Gotta love top down raglans for a custom fit!
The large gauge of this yarn really made this a quick knit.
You guys were totally right about these buttons! I love them!
I cast off with a picot edge to give it a little more pizazz....
All in all it was a great knit - simple and quick and beautiful.
