Thanks for all the input on facebook and here in the comments. I did it. I finally ordered fabric.
I ordered enough of the Dolls Cream fabric to make the book sling. Even if I don't end up using it for the sling I do really like the print and I think it could be a sweet dress or skirt as well.
But, since I'm super indecisive about it still I ordered a quarter yard of a bunch of other prints intending to make bunting. If when they arrive I decide I'd like to make the sling out of something else I'll just make another order. I'll also wait to decide on the quilt until the fabric arrives. All of the fabrics I ordered are from the Playhouse color story, but I also ordered Just Stay Little Lilac so I could see how pink vs. purple it is.
Thank you so much for all your help. Keep your eyes out for a cheap solid pink quilt for me.
