I made my very own marble magnets a few days ago. I just love making them. They are a very gratifying project. I made them with my sister a few weeks ago as well and we had a lot of fun making them. I got the idea from Not Martha’s random things to make. You can see the instructions here. These that I have made do not have magnets on them yet. I need to make a trip to the craft store. I also have to go to The Container store. They have the greatest selection of tiny boxes (plastic, paper, & metal) that these little magnets fit perfectly in. I’ll probably end up giving these away because it’s so much fun to make more!
