decorating jam jars

I've used some sparkle threads I've had for some time to decorate some jam jars that our church is going to use for the childrens' service. You place the threads between 2 sheet of tissue paper and iron on 'silk' setting and then peel away the tissue and gently glue the fused threads to the jar. You can make a thick 'fabric' if you want. I needed the tea light to shine through.
