Fifty Percent by Weight...

Maybe.  My plan to compensate the yardage discrepancy is not quite working out but I think I'll let it go.  If the second half is similar to the first this will be 52 inches long unblocked.  I anticipate that it will lengthen considerably when I wash and block it as silk and alpaca are wont to do.
I think it looks good though. The actuary should be pleased.
