Hi and welcome.. I'm Mary Moody, also from The Woodlands. There are several Janome dealers in the area (though Joyce Godfrey was one of a kind!) There is the Sewing & Vacuum Warehouse on Texas 249 and the Humble Sewing Center in Humbe on Hwy. 59. Hancock's in Conroe also carries some Janomes.
I also buy accessories like bobbins, feet, etc. for my Janomes on Ebay or Amazon at good prices. I would think Sears should have bobbins for Kenmore.
