Thanks so much for the information. I have the Mattel version from 1974. I had considered the hat idea, joining several tubes of decreasing sizes. For me, attaching the tubes would add a lot of time to each piece, and I'm on a deadline.
I don't particularly care for the Granny circle or "puff" patterns in the book, but do think these would be adorable embellishments on my scarves and hats. Once I get the basic knitting done on the 100 sets, I'm hoping I'll have time to decorate a few further using scrap yarn and the small circles, maybe including buttons, beads, etc. in the center of the circles. I think the small circles would be a cute substitute for pom-poms on the top of a hat.
I picked up 35 skeins of baby yarn at Goodwill the other day, with a quantity of matching dye lots. The yarn is thin and I think it would work well for making tubes and circles.
I have the instructions for making the circles. Do you have any helpful hints I need to know before starting? Any tidbit most graciously appreciated!
