I just had a great idea, (and no, it wasn't in the middle of the night when great ideas usually pop into our heads), no, my idea came to me in the bathroom.
I am going to make a range of bracelets that also come with a chain to make into necklaces.
Using toggles for the clasp on the bracelet and putting a toggle of the same kind on the chain you can easily swap and change.
Look out for the range.
