So, you found the site, did you check out the Blog with all the giveaways and reviews? Go on, go on check it out, I will wait some more.
So in a nutshell: the sampler is a box of goodies that is made available for sale on Etsy once a month. Independent fiber artists contribute samples and promotions making for an incredible opportunity to learn about new artists and get a feel for what they create before shopping. In addition to samples the box contains business cards and coupons to aid and enhance your next shopping endeavor.
Just to warn you, when the boxes are made available for purchase - they go FAST. Here is a link to the mailing list to get a notice of the date and time they will be listed.
So why am I telling you all of this?

Because I am a contributor to the June box - themed "Oceanic"

A total of 50 handpainted Falkland wool top samples in a never released 'mercer's pier' colourway are packed and ready to ship to the sampler HQ for distribution. In addition, I am sending a four ounce carded batt for giveaway to some lucky PF blog reader!
Be sure to check out the Phat Fiber Blog for your chance to win!!
... did you really think I would show you the colorway?
