What are some good ideas for home made baby gifts besides diaper cakes and quilting?

My sister-in-law is having her baby shower in one week and I am just so excited I wanna create more things! But don't have that much money as I am a college student so I have already made a diaper cake and baby sock rose bouquet is there ANY other things to create that do not require knitting/quilting? She is having a baby boy! :)
