Inspiring Quilters, Stitch by Stitch
Try SewEzi.com, for a portable fold up table with a cut out for machine, or sewingmates.com for just an extension table. When l purchased my Janome, it had one as a bonus from the Janome dealer. FWI, the 2014 is the 2013, 2012 exept for color of face plate, so if you find one that fits those, it'll fit yours.
Thank you. Also found a really nice one (with rulers, circle markers etc.) on sewsteady.com.
