Back home now & have spent today:
50p Edward Bear Club donation (get coffee, snack & drinks for kids & grown-up company & help, so excellent value
)
£5.92 Co-op on 2 blocks Cheshire cheese, 2 bottles Pepsi & 10 free-range eggs - should have been £9.00 but had various reductions & offers 
10p on motorbike for DS1 at charity shop. However, he has been playing up all afternoon, so will be allowed to have it once DH is home at about 7 if he has been a good boy for the rest of the afternoon [strict mother emoticon)
Found 1p on street to go in pig!
Think I will also sign up to Weightwatchers online, 10 months is too long to use baby weight as an excuse & I am running out of jeans that fit! Cost nothing to sign up as will be getting 3-month plan & then should be £32.85 but will get £15.15 cashback (& will check this is best deal), so £17.60 for 3 months, not too bad - just got to stick to it now!
Second the ideas of video, jewellery making for 11-year old girls! Also, could get each girl to bring 1 flashy/pretty item of clothing/outfit/jewellery (but not an expensive one) & have fashion show, complete with bit of make-up, hair, photos (even better if you can print these off at home & have as part of party bag)?
