It turns out that the Christmas blanket/rug was crocheted with double and, sometimes, even triple strands of sportweight yarn. No wonder it was so Dense!!
With DH’s help I now have plenty of red/green/white variegated yardage, some with a fine strand of silver sparkle and some plain.
I started another Christmas ripple as soon as we finished winding the first ball. Maybe I’ll be able to show you the blanket on Monday!
