I think you have fallen into the same hole as I had on the front edge. The diagonals would have been better finishing one more hole to the right. :frown:
It does seem hard to do that last under weave, depending on the location of the holes on the rail. Having a spray bottle on hand to spritz the cane and help lubricate the pull seems useful. The good news is that it doesn't seem to affect functionality!
Have you got a wider cane to do the finishing trim? It needs to be more stout than the rest of the weave to help give a little cover up.
