Paint the jar lid and set aside to dry. Measure the cardboard core to at least 1/4" shorter than your jar. Spread glue on the outside of the cardboard core and arrange buttons or hardware trims to totally cover the core. Trace a circle the size of the inside bottom of your jar on the felt and cut out. Spread a very light coat of glue on one side of the felt and arrange to cover the inside bottom of the jar. Put glue on the bottom edge of your decorated cardboard tube and place it into the jar and press firmly against the felt. If room permits add additional trims, notions, hardware, etc. between the outside edge of the decorated cardboard and the glass.
For the ladies glue your doily centered on top of the jar lid and arrange prettiest buttons and charms to your liking on the doily and glue in place. Add bow.
For the man on the painted jar lid arrange a variety of the hardware, small screwdriver, pencil stub, etc. in a design that pleases you and glue in place.
