Medallion Plans on site

The Medallion plans have been considered proprietary, until now. Jennifer Crock, who designed the Medallion Cabinets, has given me permission to place the plans on my site for downloading.

A customer, Mr. Cobham, was kind enough to draw up the plans so they could be distributed.

Any commercial use of this product should still be licensed by Jennifer through Jena Labs. Non-commericial use is free.
