I love stationery and any other paper goods, and I know out there there are many others sharing the same "guilty" passion.
I could make a long list of items and shops, but today I wish to recommend you only one of them, a lovely and successful shop I found on Etsy. It is called krazykatedesigns, and I love it. Here you could find paper and felt supplies for crafters and not only, tags and postcards, rubber stamps and even ephemera and vintage items, anything you need for your projects and if you can't find it just get in touch with the seller and she will do her best to help you.
This is the secret for a great business, a friendly owner and an interesting stock.
Take a look at the window beloww to get an idea what I'm talking about:
Take my advice, visit krazykatedesigns, check frequently and don't hesitate to get in touch with the seller for more information.
