Fantastic ideas ladies!

Has anyone tried making mobiles? Use a branch and tape/tie/glue on found objects from the garden. Or a sea animals mobile using plastic takeaway container lids, cover with scrunched coloured tissue paper then draw on features and add crepe paper/ribbon strips for tentacles/fins etc (looks good cos it's kind of see through still). Or cut out cardboard shapes and decorate then attach to a coat hanger etc
What about weaving? You can use old hessian bags (remove some threads) or onion bags and weave wool/ribbon/paper etc
Straw painting - blow blobs of paint around the place with straws and use the finished pics for wrapping, stationery, covering boxes etc
And what about salt dough - make whatever you want (like clay but less messy!) then bake and decorate it - great for beads cos you can then make MORE stuff!
Make your own dress ups - masks, decorate plain clothes/hats with tails, fins, fabric crayons (saw them at Big W for only a few $)....
Stained glass windows using cellophane to cover shapes cut from cardboard.

I keep the little bits of ribbon from inside tops (you know, the shoulder hanging up bits!!) and have a HUGE stash of coloured ribbon, all free! Old CD's apparently make great mobiles/fish scales (shiny).

So far DS (13 months) likes drawing for about 30 seconds at a time, ripping paper, pulling stickers OFF stuff and throwing playdough (with the occasional taste-test).... can't wait til he's into crafty stuff!
