I am sure you have many spools lying around and do not know what to do with them. Well, one way to use it is for bird feeder's base and a roof. The design has been tested for the past couple of months and works fine. If a top or a base is loose, try some super glue to keep it at a place. There are drain holes in each of the four feeders to keep the feeders dry. It is perfect bird feeder for your porch or back yard with a honeycomb pattern.
[Prusament honeycomb spool]
Right now it fits only to Prusament spool, but with small modification and some extra holes, it might conform to any other spool design.
The sunflower is the birds favourite food. Please, bear in mind that birds are small assh*** and waste could be all over your porch.
