The answer is a definite "YES." Links are one of the most powerful aspects of the Internet. You want to give potential buyers every opportunity to find you. Etsy is an easy convenient online marketing site that most anyone can use. So use it to your maximum advantage. In addition, links between your site and Etsy, back and forth increase SEO (Search Engine Optimization). The more traffic the better. Search engines use traffic as one method to rank your site.
I took a look at your Etsy shop and web site and have a few other comments.
On your web site, I would recommend a simple sentence like Shop Online Now instead of an Etsy icon or widget . These motifs (like an Etsy E) may not be recognizable to all viewers of your site or match the aesthetic design of your web site. Note how this is one short sentence is so effective on Kate Cusack's web site by CLICKING HERE.
There was another problem with using the Etsy on your website. When the page opens, the Etsy "E" was below the edge of my screen, below the "fold" to use a newspaper nomenclature. I didn't even see the Etsy "E" the first time I looked on your site.
When I went to your Etsy site I also noticed that you are not using your full tags or writing a complete descriptions on every image. This is very important for SEO. In fact, it is an absolute necessity. Tags and descriptions are how search engines find your work. If search engines can't find you, neither can your customers. Etsy has tons of informative posts about this topic of the Storque. Here are two great topics that will be helpful to everyone even if you don't sell on Etsy.

I also noticed a fabulous necklace on your Etsy shop (left image). I made some adjustments using PhotoShop (right image) by brightening the image and increasing the contrast. When selling your work online, your photos are the primary vehicle you have to sell your work and they are not doing their job unless they are fabulous photos. Learn to use PhotoShop or some other photo editing software. It is an essential skill in this digital age and necessary for successful marketing.
I also worked on the two photos below, the left image is from your Etsy site. The right image is brightened and I added a speck of contrast. Don't you think it looks better?
I learned PhotoShop using Lynda.com. It is so easy with their online video tutorials. I love Lynda.com.In the past three years I learned how to work on my web site with Dreamweaver, Illustrator, and there is even tutorials on social networking like twitter, Facebook, and Flickr. The money I spent on my subscription has saved me tons of money and time; this is the reason that I signed up to be an online affiliate.(A purchase from Lynda.com helps keep this blog going.)
Hope this information is helpful. There will be no post on Thanksgiving...but wishing everyone a thankful holiday. Become my friend on Facebook to see last year's Thanksgiving table. I will be posting pictures of my 2009 Thanksgiving table as soon as the table is set. This year'S theme is a "classy, brassy, gold and grassy". Wait till you see it!
