Update! I took one of the inserts over to the sewing machine store, and they tried it in the Gidget sewing table they had. It fit perfectly! No rattling around. But, that table did not have a "lip" for the insert to rest on. That's why it was fitting over the top of the opening. It turns out that they changed the table, and the newer tables have a lip inside the opening for a flush insert. The table the sewing machine store has, was an older model. Gina is ordering me two new inserts and they are taking back the other ones!
They order the inserts from a different company than the one that makes the tables. So if you order a Gidget or Gidget II table, make sure that you find out what the cutout looks like so you get the correct insert!!!!
Happy dance,
thank you all for your encouraging words. Lorchen, I'm sorry that you won't be needing to come over here and talk with Tim - I think you two would get on very well, actually. But I would love to have witnessed the conversation!
