This seller is local and I woudl be able to go pick up a sling tomorrow. But I would love your guys opinion first.
I know I am a little late since you already ordered one but I would be concerned about the material she is using. The pictures of the different ones there is one material that I know is not ring sling quality material. The black with the gray swirls to be exact, it is quilting quality fabric which is NOT OKAY to make a ring sling out of. I know because I have bought some of this fabric, here is a link so you can see for yourself: https://www.joann.com/keepsake-calico-fabric-black-scroll/xprd862730/
Also here is a link to give you more info on what material is okay for ring slings to be made out of: https://www.sleepingbaby.net/jan/Baby/fabric.html (this is the same lady that makes the SBP slings which are really good)
