I saw you asked me a question about my bedding in my nursery post below, but I didn't want my response to get lost in that post.
Yup! I got that applique tree on Amazon. It was totally worth the $40!
So, my mom actually made my bedding, but my inspiration for the bedding was the My Baby Sam Pink Paisley Splash bedding set, which is also on Amazon. Here is the link:

Good Luck with your nursery!
