I love Etsy's system of being able to mark sellers as "favourites". My favourite thing about the bookmarking system in Etsy is that you see a list of your favourite products/stores, and you you see a visual picture of each store, which means it's super easy to remember WHY you bookmarked them. It saves me having to go through a list of favourites, wondering why I saved their link. (Like in my Internet Explorer - with 2,000 links I've saved)
There is no rhyme or reason to this particular collection, other than I think their shops are super sweet! From Top to Bottom:
stitchface - OMG - you have to look at their super cute stuffed animals.
zukzuk - She's gotten a lot of press for her prints, so you may already be familiar with her work. I adore and admire her work.
pinkpandafabrics - A collection of amazing fabrics that I'm drooling over. Eye candy for the crafty. :)
