I personally would make an I-Spy quilt for the baby..in 6 or 7 months, it will be ready for it.
so sad this has happened to you. your SIL is rude. it happens to most of us. I am still waiting for 3 thank yous for 2 wedding quilts and 1 baby quilt. if i didn't have tracking on them, i would of never known they got it. it has been over 3 years,for one, and they all live out of state..family..humpth!
on the other hand, my DD's best friend asked me to make a baby quilt for her soon to be born son..i was so honored and touched,that she even paid attention to my quilts.
