When sawing unseasoned or damp wood with a tenon saw, spray the wood with WD40. The saw will cut through much easier.
If you are sawing plastic, put a strip of masking tape across where you want to saw, mark your length then saw, it wont split the edge then.
In the garden in spring when the flowers die off and you are left with lots of green uninteresting leaves, put some nice fabric (not plastic) flowers amongst them, they look great next to the real leaves and give you extra colour.
Need to economise on the kids cereal, stir some Rice
Krispies into their favourite Coco Pops and shake well.
