We have always made do, done it ourselves, resisted buying "stuff" just for the sake of having the newest "stuff" and tried to grow much of what we consume in the way of food. Our home is comfortably furnished with a rather eclectic mix of hand-me-down, home-made and cast off furniture and I don't own many gadgets. I don't see any need to change any of that just for the sake of changing it.
It's a good feeling to produce a meal when you know it came fresh out of the garden minutes before it was cooked. Here's what we had last night: spinach souffle; oven baked pink fir potatoes; corn on the cob and fresh tomatoes. Our summer garden is almost at the end of production, but vegetables to carry us through winter are either stored or quietly growing away in the garden.
As far as possible, I try to carry this anti-profligacy message through in my work as well. I don't throw much away (anyone who has seen the inside of my studio will attest to that!). I can always find a good use for something that others might pass over as useless junk. For instance, a while back, I devised a way to make an excellent sculpting material from sawdust and glue and made quite a few dolls using it - I even won a recycled-materials design award with these dolls.
And just this week I have been knitting up a storm using scraps of leftover wool - even the tiniest bits can be used. The mouse is of my own design....it was fun and quick to make!
I'll climb down from my soap-box now, but will conclude by saying that you don't need to be spending bucketloads of cash on fairly useless stuff in order to be happy - you can live very well on considerably less that what you think you need and if more of us did it, the planet would be the better for it.
