Please listen to Jan in Va. She has the best advice on this. And KyKaren1949's link to robinsonswoodcrafts is the perfect place to go. I have no affiliation with them, but I would really love to own one of their ladders. I think your mom would be very pleased with one of those for displaying at home or elsewhere. I have many racks like you are looking at and what Jan says is so true -- you really only see the one that is in front. I know you want to surprise mom, but this is one time that I might advise showing her pictures of all of these and letting her choose. She'll love you for all the time, thought, and energy that you are putting into this gift.
