Something that works with me - when it comes to the machine or whatever
Show me "how" - then let me "do " it. I can be told and told, but until I actually try it, I don't "get it"
Example: Thread the machine - then unthread it and have her do it. (more than once, if necessary)
Have more than one bobbin available - you wind one - then have her wind one,
Etc. etc.
I think it's important to have something they can use - and that making to fit will not be a problem.
