Dd1 is now in Yr 10 and dd2 has started in Yr 7. They have been back at school since last Wednesday. So far we have had requests for:
£3 for sketchbook (dd1)
£5 for food tech ingredients - only some of what's needed. The rest (the expensive bit - fruit, meat etc) we will need to send in. (dd2)
£6.75 for fabric and a zip for dd1's first textiles project.
£5 for other textiles equipment
£2 per revision guide for science for dd1 - 3 guides = £6
So that's £25.75 all in.
When both girls started in Yr 7 we were asked for a voluntary contribution of £5 to the school fund and were told that was the only time they would ask for money. Ha! 
We are happy to pay whatever is needed of course and fortunately have the resources to do so. It does seem to me though that this is pushing it a bit. Or is this typical?
