I would not worry, if you started at $24 that is fine. Most people go with gift cards anyway.
People will get you what they want to give anyway, and they will stay in their budget. Some people like to give the same thing to everyone, easy for them and fair and square for multiple relatives who tend to keep track of what you gave to each one of them. My Mom back in the day gave a good quality tea kettle, copper, from the high end department store.
But your Mom in law might have a good idea, some people like me like to get a box and fill it with stuff. A selection of $24 dollar items would have me loving it.
A friend's daughter got hung up in tiny details, and did not know what to put on a registry. Her hubby to be had forbidden her to register thinking that was trolling for gifts, but was told by his mother in law that he was being a stupid jerk, how would people know what they needed? He changed his mind a week before the wedding. I gave her spatulas and measure cups, etc. I never got thanked, so I guess she hated it, but why them put it on a registry? Nobody else had touched the little stuff. Maybe they knew her. Found out later that she and really stupid hubby would have preferred big ticket items, sure, I'm gonna go buy them a big screen tv, I had never met either one of them, the bride's Mom was a co-worker. They thought that Right until her new hubby went back to work the day they moved, left her alone in the apartment and told her to have dinner on the table when he got home. She had nothing to cook with, and called her mother to cry on her shoulder about it. Her Mom was unsympathetic, and told her so.
So, to each his own. If you want china, put china on the registry. And try to put several items of all price ranges, and let people know gift cards for that store are great, you will buy what you did not get after the wedding. You might someday be glad you asked for 2 salt and pepper sets.
