Step 8: Completing the Bracelet
The best way that I found to complete this was to curl the bracelet as it will be when finished, and take one of the last metal rings. Push the ring through the last two rings from the end, and 1 ring on the joined side. Close this ring, then take another metal ring and complete the same column. Push it through the last rubber ring and the first two on the joining side. It should get a bit easier from here on as the bracelet will stay together because of the first column.
Continue across until all the rings are in place. These last rings will be a bit awkward, but they will make sense, as they will look like every other ring when complete.
