Jar lids come in all shapes, sizes. They are found on jars from spaghetti sauce, pimentos, pickles, salsa etc. Since they are so perfectly round, I thought they would be great for ornaments and crafts; so I started keeping them instead of throwing them away. I even have my students bringing them in for a seasonal craft. It started when I decided to piggy back on a magazine idea for "repurposing" Christmas Card photos to give as mementos back to the families. But the possibilities are really endless; once I started working with them, new ideas keep coming and I haven't preserved any Christmas Card photos yet. And I guess great minds think alike because I also saw them used on the ornament girl blog, if you google it, ornament jar lids, you will get hers and a ton more! I just did it! See no idea is really new!! DISCLAIMER: I generally like to come up with my own crafts and use my own brain and devices. I prefer not to copy and don't use Pinter...
