Attach the chains to the bookmark with the lobster clips. Attach a 'handmade' charm if you wish.
This is how to make beaded bookmarks. You will need headpins and wire as well as the bookmark blank, a chain and beads.
Attach a jump ring (open with pliers) to the bookmark and cut 2 lengths of chain. You will need to attach a lobster clip to the end of each piece of chain. Making the book mark with lobster clips means that you can take part of it to make a matching bag charm.
