All of your answers are very interesting. I told him again he was going to have to learn and he said that he was scared he would mess something up. He also said the bobbin and case was too little and he didn't think he could hold on to it to put it in anyway. Oh, well, I'll just fix a few up for when I'm in a hurry and snap them in for him.
In the mean time.... You are right. He did learn how to do this just so he could be close to me while I was in here on the computer or while I was on the other machine.
The way I look at it is. If he tears it up... oh well... a shopping we will go!!!!! thanks you all for taking the time to give me some suggestions.
