Things for holding a pencil properly

[scrappydappydoo]

DD1 is in yr R. I've just sat her down to write a Fathers day card and I'm horrified at the way she actually holds her pencil. I'm part at not noticing it before but its really bad. I seem to remember when I ws a kid you get these triangular pencil holder things that go round a pencil and 'force' your fingers into the right position. Does anyone now where I can get these from? or something else to encourage her to hold it in the right position? TIA

I did some work with ds1 last year to improve his grip and the best thing I found was to get him to write on a vertical or near-vertical whiteboard. Apparently writing in this position encourages the correct grip - not sure why. Anyway, the novelty meant he was quite keen and did loads of practice, which probably also helped and he now holds his pencil perfectly.
