I thought I would show you what I did with mine several years ago.
I have called this Art Quilt "A Cup of Tea and some Rusty Nails.
It measures 85 cm x 5o cm .
The base fabric is a piece of recycled fabric left over from a skirt. The blocks are made from used tea bags -which I wove into a 9 patch block and adhered to a fine iron on interfacing.
I ironed on some gold foil to give another dimension and I then bordered the blocks with the rusted fabrics.
Other sections were hand stitched with either the thread that I had tied around the fabric when it was rusting or a tan broder cotton.
I have also attached a verse to explain the process of how the quilt was made etc.
About used tea bags--what you do is save the teabags with the tea still inside and leave them to dry(on the window ledge).
When they are almost dry you open them and removed the tea from inside and there should
be a lovely brown mottled tea bag left--that is if you don't squeeze all the liquid out into your tea cup before hand.
I probably should have treated the tea-bag section in some way to preserve it but I didn't so who knows how long it will keep - but what the heck it is a good talking point anyway.
