When they arrived I was very surprised with how small the beads were after working so much with the Midi beads - they are about a third of the size, and really, really tiny! Really the only way to manoeuvre them on to the peg board is by using tweezers, and it's very fiddly. More than once I managed to knock the board and send them scattering, and I found out that it is very important to keep them out of reach of fascinated small children!
They looked a bit uneven when they were on the board, but once they were ironed (very carefully!) they became a lot smoother. I've started with the Christmas set, and made a lovely little Angel and Father Christmas. I've made one of each and there are plenty of beads left over, definitely enough to make another set. I've just propped them up in the Christmas tree for now, but I might attach some ribbon to them so that they can hang up.
I think that I particularly like them because they resemble cross stitch, which I love to do but it takes me a long time. It's very satisfying to complete a picture in one go. If you love Hama beads too I'd recommend having a look at the Mini beads, they are a grown up version of a children's craft!
