Keep in mind that boundaries are not something you 'do' to someone else. They are what you place on yourself.
While these two incidents are certainly annoying... I see no boundary that she has violated. In the first instance... you cannot control what she does... you expressed your opinion. Period. End of story.
In the second incident... the boundary is what you are willing or not willing to do in terms of remodeling. Her comments don't change that.
Your annoyance at her behavior CAN change. You have complete control over that. Or not. You can be annoyed.
The only time when I would see a boundary being violated is if your MIL hired a redecorating crew, had them show up to your house, begin construction, etc., without first discussing it with you. Even then, you still have control over the situation.
If you don't like how your MIL is treating you, then YOU can decide not to be around HER. That is a boundary. To expect her to change HER behavior to suit your preference(s) is a control issue.
