I was a bit disappointed with my first attempt at a Christmas jar lantern a while back so I’ve had another go.
I’ve used white tissue paper, which proved to be quite delicate and fiddle farty to use. I applied one layer as evenly as I could, and then, when it was dry, put a packet of Anita’s Snowflake Glitterations on top. This may seem a bit of an extravagance, but I bought them last year and was never inspired to use them. Next followed another layer of tissue and then several coats of Ronseal Quick Drying Clear glossy varnish.
