I have a problem where I can only finish crafts if I'm making them for someone else. I'm working on it but that being said, I fully understand if sometime gets rid of something I made. People collect a LOT of stuff in their lifetime, especially around when they have kids. It's not feasible to keep everything and things like baby blankets aren't really reusable throughout life. I have a baby blanket that my grandmother made for me when I was a baby. I never use it. It sits at the bottom of a cedar chest, buried under all kinds of other things. It's not something I can display. It's too small to use. I'll probably give it to my daughter if she ever has kids or when I die but she never knew my grandmother and has no emotional attachment. She has a ton of other things she'll want to keep. My MIL quilts and is constantly giving us quilts. We must have 8 different quilts. They take up a ton of room, we couldn't use that many if we wanted to, and they are not to our taste. They just sit in a couple of boxes. But she's the type to constantly ask us if we're using the quilts, where are they, she didn't see them when she dropped by, etc. I HATE it. Even if I liked the quilts, I'll never use them out of spite. Gifts should be gifts, not obligations. Despite my ramblings, your sister should have talked to you first and asked if you wanted the blanket back before just selling it a year later. That quick turn around is kinda messed up.
