Before starting the process, first we wash and dry the glass jar well, because I'm sure you don't want it to leave a stain when the decoration is finished?
After drying your jug, you can fill the jug with artificial snow as much as you like. In this section, you can decide the distance from the snow. Wouldn't it be nice if you put a miniature pine tree inside and a sleigh next to Santa Claus ...?
You can create an atmosphere like snowing from the cover part with the help of fishing line and glue to make snowflakes as in the photo.
When you use artificial snow, you don't need any additional glue, it just sticks where it touches.
Later in this study, a little epson, bath salt, was also added on top of the snow. Necessary? Of course not, just a small detail of your preference :)
