I need advice.

I am trying to put work harder and expand Argyle Whale so that it can sustain me as a full time job but I seem to just be running around in the same circles just more frequently (ie Etsy, this blog, Flickr). I need to find new places to be seen. I especially need to find more boutiques to sell my items and new websites to advertise on. If you can think of any stores around the country or websites that you think my items would compliment, I would be grateful for the tips.

Here are some of the shops I already have in mind:
Magpie
Renegade Handmade
Cog & Pearl, Brooklyn
Rare Device
Jenn and I made these nice little solicitation bundles (see pic above) with a letter, a journal and some notecards to send out to the shops and hopefully peak their interest.

Here are a few sites I plan to use to get myself seen a little more:
Pika Package
Illustration Friday
Paper and Stitch
Modish

Any advice on how to proceed or hints to where my items would be welcomed are gratefully accepted!
