Marilyn,
Took a quick peek at your shop photos and if I may offer a few suggestions:
Shooting several different angles is helpful because it also offers different lighting on the object; and you might consider including a shot of the back of the item too.
Generally your exposures seem fine and your backgrounds are nicely simple; but your focus could be better.
Stand back a bit and use a larger number f stop (4.5 works well on my digicam's macro setting) and remember to aim your auto focus to the area closest to the camera (i.e., viewer) so that the foreground's clearly focused.
Good luck,
Dan
