Look what arrived today!
My two FlexeeLooms. The heart-shaped loom is the first book put together. All those links come in cellophane packages that contain square or rounded ended pinkish or purplish two pegged units. There are tons of YouTubes of folks unpacking these fun pop-beads of knitting. Do any of you remember pop-beads? I think that was the 50s? I loved them. You could make a necklace or bracelet out of them. These peg-units are a bit stiffer than the pop-beads of yore but as I understand it the stiffness helps the loom-knitting to be done without breaking apart. I can’t wait to play with these. More, I mean, with yarn. With seven socks in the making I need to wait a minute to play. Here’s an unpacking YouTube.

I can’t think what you would need a heart shaped loom for. No doubt you will show us in time?
It’s flexible. I just moved it to look like a heart. I;ll probably show what I’ve done on the hat I’m working on on Friday. By then the shape of the hat will show up and I will be even happier as I am loving playing with this loom.
Can you do bigger things on them, like jumpers?
Yes, and blankets. I can’t wait to try!
