First you need to clean some jam jars really well and remove any of the old stickers. I had some square shaped jars which I thought worked really well.
Using PVA glue cover the whole top of the lid and around the sides. Glue down some fairly thick plain white fabric to cover the top and sides, then trim away the excess. This is to give a white background to the floral fabric you stick on top so that the colours of the lid do not show through.
Cover the white layer with more PVA and then stick down your floral fabric, allowing around an inch of excess fabric around all the sides for tucking in underneath. Glue the inside rim of the lid and tuck the floral fabric inside, pushing it right up against the edge. I found it helpful to rest the lid loosely back on its jar with the fabric wedged in underneath to help hold the fabric in place while it dried.
Once dry you can fill the jars with your favourite sweets! I used some string and made little paper tags to decorate my jars but you could use ribbons, flowers, pom poms or whatever you wanted to decorate your sweets supply jars!
