Hi Kirsten!
I don't know how far you are willing to travel, but Scottsdale has a weekly Artisan Market in Old Town by the Waterfront. I believe it is held Thursdays and Sundays. There used to be one other childrens apparel booth and I think your room decor items would fit right in. I haven't been in a few months but I think it is still going on...
Here is the link to apply to be an artisan vendor:
