I like my items to be pink but you can do any color you want. It is best to have most of these items yourself so you can have your items picked up from your house and not have to take them to the post office.
Most of these are ones I have or am looking into getting very soon.
You can use anything really as a cart. Even just regular racking.
I make faux leather bows for young girls so these are the materials I use for that.
