I'm obviously not Caroline, and I have only used Toho seed beads for looming so far, but they did not make me happy. Those were only two colors, and maybe it was the matte surface, for some reason I like shiny beads better for looming even I do use matte ones, too.
I thought these links could be interesting for you if you don't know them yet, though.
Very complete explanation about the beads, thanks, Cat. I have also bookmarked both sites for future reading. I'm with you, the shiny beads catch my eye. That was one thing about the first loomed bracelet that I didn't like: two colors were matte finish.
I think I struggle with them because they don't like to pop in between the threads easily, and I wouldn't make a piece all in matte beads unless I have a special reason for it, but a combination of matte and shiny beads can be great for contrast.
A friend of mine made a great bracelet for me in a swap with a matte black background and silver lined beads in different colors for the text, the text pops off the background!
Obviously I am Caroline...I think. Yes I have used them a couple of times and they have worked well. However never try and mix them with Delicas as I accidentally did once. They are different sizes and you will end up with wonky work. x
Just like a curly wurly, nice and sweet but a little bit twisted.
