This is a quick and easy craft and doesn’t have to be just for Christmas.
Collect up used glass jars and give them a good clean. If you don’t want to freehand on a design, draw it first on paper and then push the paper inside the jar so that the pattern is easy to follow. Use a glass decorating pen to make the outlines. I used gold and have done a number of patterns- stars and snowflakes are my favourites! If you’re feeling adventurous you could use glass paints as well- holly looks really good.
I use the jars as tealight holders- tie a pretty ribbon around the top. You can always use this idea to decorate jars if you make jams or chutneys for gifts. Probably wont survive the dishwasher afterwards though!
