A "magic ball" is made of yarn scraps tied together. A "scrumble" is a free form crochet piece.
This was made starting with a black flat circle made in dc, then the next round started with the "magic ball". Whenever a new piece of yarn started, I made a ch 3, turn and went back in the opposite direction.
This is a scan of the piece, pretty much centered (quite a bit hanging over the edges of the scanner)-- it looks like a multi colored amoeba. The yarns are various types and weights-- including several novelty yarns. After the "masagic ball" was used up, I made an "outline" round with a white yarn. I have a new "magic ball" started.....
