that is odd...according the RULES of Hobby Lobby, that would be a conflict of interest! You as a HL employee are not allowed to be a "contracted" teacher!
Also if you have never taken or taught a beginner class...you might want to rethink it. Months of planning and prep goes into it and you will NEVER make any money at it! If your HL is like most, the class room can barely hold 4-6 people! Not nearly enough to make it profitable.
I taught our HL once..and won't do it again. The people want the classes for FREE...so many signed up, and yet only 3 came. It was a nightmare!
Now I did it for Hancock's and wow..night and day! I think it has a lot to do with the the customers perception of the place the class is held. Hobby Lobby, sort of carefree, maybe not into sewing so much as artsy stuff, and at Hancock's it is ALL about sewing, fabric, notions, machines, etc.
