I was waiting to reply until I could take some pics or measure. It was too dark today for pics, but I measured the aran wt yarn sample and it was over 9 yds. The yarns that go on sale on Tuesdays are the ones they send the samples of at the beginning of the month. They also have a free color flyer about the Tuesday yarns, but if you buy the sample skein subscription or the color card subscription, the flyer will also include 3" color snips of the yarns.
So far I’ve knitted some of the little skeins into swatches to see if I like the yarns enough to buy. Sometimes I even wash and air dry them. Helpful because my mom said she didn’t like the smell of alpaca! It’s been really worth it to me because I started off not knowing much about yarn and playing with the samples has educated me a little more than fondling them at the store. It’s been hard not to buy too much, but I manage.
I had planned on eventually making a scrapy scarf or purse, but haven’t yet - except in my mind! I’ll try and post a picture when I get a little sun.
edited to add that Elann sometimes sneakily adds new yarns on days other than Tuesdays, but the subscriptions don’t include those. You have to keep checking ‘sneak peek’ on the home page.
