OK, I'm gonna try and do a comprehensive list of projects and and general cost. I couldn't be happier with how this nursery turned out. The room is TINY! To give you an idea, that's only a 30 inch fan...meant for like laundry rooms, lol.

And his clothes are organized in hanging organizers in the closet.

I reupholstered the chair (the chair was $20 used, I spent about $50 on reupholstering supplies)
DH painted and installed the chevron board around the room. They have tube lights mounted behind them!! I'll take and post pictures of them "glowing" tonight (perfect for mid-night breastfeeding and diaper changes). (I have no idea how much this cost, but it really wasn't much. It's two strips of tube lighting and like 3 wood boards)
I made the mobile (less than $10 in all, inspired by this $90 one from Etsy - https://www.etsy.com/listing/95396492/baby-crib-mobile-baby-mobile-dr-seuss?ref=favs_view_12 )
I sewed the chevron curtains/sheet/changing pad cover/basket inserts (I'm too lazy to look up how much I spent on the fabric, lol)
DH painted the ceiling fan (the fan was on sale for $28, we used paint left from the chevron board project)

The banner above the large window and the alphabet prints above the closet were purchased from Jo-Ann Fabrics (no idea how much these cost, they were purchased early in the second trimester, lol)
The red curtain was purchased from Amazon.com ($20)
The crib and changing table were purchased used. (crib was $75, the mattress was DS1s before he moved out of his crib, the changing table was $60)
The changing pad was purchased new ($17)
The two baskets were from Michael's. (They were 50% off and cost about $12 each)
The tissue paper poofs were from The Paper Lantern Store
The hooks on the wall were from Target (and were used in DS1's room until he potty trained)
The hanging wet bag was purchased from KellysCloset.com
The prints on the wall were actually reusable shopping bags from Target in frames from KMart that were on clearance (each bag was $1, each frame was $5.85)

The basket hanging from the wall hooks was from DS1's Baby Shower
The Seuss blocks were a gift
