Some random things we've done that are fun, (our boys have had a tough year, so we have tried to fit in lots of good things alongside the difficult memories over the months)...
Letter boxing on Darmoor, like geocaching only low tech!
The boys being 'chefs' once a week, and making a posh meal for me and DP.
Camping as much as possible.
Planting trees, and fruit bushes.
Lots of dressing up, and having 'concerts', and discos.
Boat trip to watch dolphins.
Home outdoor cinema, in a field with a few sheets sewn together on a scaffold pole, and a projected film, hay bales and blankets to lean on, and a hotdog and popcorn stand, great fun!
Teaching them to sew, and to crochet on pins
Helping them to have a charity stall with home made crayons.
Crazy face/body painting.
Slack lining. I'm rubbish, but boys are getting good!
Making felt, collecting sheep wool from fences.
Making jam after picking berries, making wild garlic pesto, making elderflower cordial.
