Couching Dilemma

I had a feeling this was going to happen, I love the indigo and tannin dyed sisal so much I used it all up.  So do I go start a new indigo vat, which won't be ready until Saturday to use at the earliest and that coincides with my yard sale which means no dyeing on Saturday, or do I couch something else down instead?  I have on tiny six inch bit left of the sisal and no idea where to put it on the piece!
