This morning I put all the magnets into the 4 formers that I’ve made
As you can see, I followed Sally 4th’s recommendations and used masking tape. I didn’t use superglue though – I just pushed the magnets in and then put tape over them. The magnets are a snug fit into the holes and they work well with just the masking tape:
The magnets will keep all 4 formers together just by holding the corner of 1 former, but I couldn’t get a picture of that, so the above will have to do!
