I did not photograph the process of tear down....
Pulling out the teeny tiny nails was not easy! I used a very small flat screw driver to pull up the little nail heads and pliers to pull them out. It took me about 6-7 hours over 3 days (because it is hard on the hands) to get as many out as I could get to. I did not save the nails but now realize those are a 'vintage' item, too (but, I mangled many of them so, oh well)!
The next step was to restring the springs. Maybe I'll photograph that 'how-to' on a future piece (I have now done it three times).
I updated the method and used plastic zip-ties instead of string and will confess here that form worked well here and I am likely to do that from here on out!
This project is NOT finished and I need to find just the right fabrics for the cushions and promise to update as that happens this spring!
