LOL at this thread and the "boxes of stuff" in your house.
I've certainly created a rod for my own back. As a child I was frustrated that we never even had card in the house, and felt tips that worked were a luxury, and as for sticky-backed-plastic ...!
So we have crates and crates of materials and resources in our breakfast-cum-craft room, paint of all different types and colours of the rainbow, every possible fastening device known to man, paper, card, boxes, tubes, material, wool, stencils, etc! As well as a general agreement that we will purchase required items when asked.
DS2 is very independently-minded and generally gets on and completes projects on his own.
His chosen task for this week is to make a bird table out of a plastic ice cream carton (we've already got a gorgeous wooden bird table that my dad made fgs) and to make "seed cake treat" ... this will involve buying lard, and melting it ... yuck! If we have to go shopping to buy lard, why can't we just buy the usual bird fat treats and hang them up ...?! [Miserable mummy emoticon]
