Recycle, Upcycle large wire spools

I got large spools used to hold wires and ropes.  I painted them to look a bit rustic or nautical.  I then bought rope to cover the center parts.  I have included some of the center dimension so you can estimate the amount of rope needed.
16 in high by 15 diameter
Requires 126 ft 1/2 in rope or 169 ft 3/8 in rope.
the plastic top measures 11.5 high by 12 diameter.
Requires 73 ft 1/2 in or 99 ft 3/8
The other all wood spool measures 18 high by 12 diameter.
Requires 114 ft 1/2 in or 152 ft 3/8 rope.

Here are two spool examples to work off of for size.
