While your Mason jar is drying you can work on the lid. You can use a thick card stock, maybe repurpose an old card or you can use a heavy fabric like felt. I used an old cereal box then glued scrap paper to one side of it.
Once the glue is dry, I traced the lid on the paper then cut it out. You may need to trim the cut out to ensure it fits in your lid. Next you’ll trace a cross on the inside of the circle then use an X-Acto knife to cut through the paper along the lines. This creates an opening for your tissue.
