Unwanted gifts from MIL?

My MIL lives nearby and she offered to make some nursery bedding for my daughter. I helped her pick out the fabric (the theme was animals) and told her the color scheme I wanted (yellow, purple, light blue, and pink). We painted our walls with this scheme. She made a quilt and dust ruffle for the crib. The problem is that she didn't use all the fabric we picked out (she only used the darkest navy blue fabric and made little swaddling blankets out of the light colored in scheme fabric). So, that's fine. We still appreciate the gift and we are using them anyway, but she also made a wall hanging and lamp shade without asking and they are also not in the color scheme. We're using them now too, but nothing in the nursery matches the stuff she made. I'm not trying to sound ungrateful, but all the other stuff I bought clashes with what she made and the wall color doesn't match either. I'm wondering how long I need to wait before I "re-do" the nursery without hurting her feelings. A year? Two years? What would be a good time frame? Since she's nearby, I can't just take down the wall hanging and lamp without her noticing. Thanks.
