I have yet to load a quilt sideways to save myself making extra passes. It is just my preferrence. I have heard of quilters doing this but I like my pattern left to right and not up and down on the quilt. She should have discussed this with you before hand and you should make it a point to tell her you are dissappointed in her doing it this way. If you don't tell her she will always do it this way. she would probably give you a discount if you let her know you are unhappy with it.
