Banded, its growing slowly but surly. Heavy is the elastic and I had begun knitting the waist part on round needles. But the elastics kept breaking with the tension and the tightness of using the round needles. So I cast off and changed back to crochet, 20 hook so quick results for this part.
My daughters bedroom rug, completed It not a very large but this rug that measures 70cm by 80cm took three single duvets and two pillow cases. I crocheted it on a 12 mm in the end as the 20mm made to bigger a hole, so not very rug like.
Now my son wants one too(not pink), luckily I have a good supply of very old duvets:-)
