My dc 5 year old twins and dd4 have just had the best hour making foil covered eggs. Honestly I had the day from hell yesterday,today has been lovely mostly due to said eggs. We all loved it.
Basically you cut out some card egg shapes(not too small),get them to cover in kitchen foil (we glued it down),paint with normal runny paint then get a cotton bud to make patterns.
They look so effective. You can use them to put on cards or to stick on the window. My lot did stripes,dots,flowers,circles,trains. Using 2 colours was very effective.
I'd cut out loads of eggs 1st and squares of foil,use prit stick,also make some up too.
Can't take credit for it was on- www.craftweekly , fab site. This weeks e-mail/newsletter is eggs,she had loads of ideas eg lovely hunt buckets made out of paper cups.
