This one has the Puff finishing off like a double. http://www.freevintagecrochet.com/af...n-pattern.html
(Puff st: yarn over needl, insert in st and pull loop up the length of a dc, * yarn over needle, insert in same st and pull loop up the same length, repeat from *, yarn over and pull through all loops on needle but one, yarn over and pull through 2 loops)
The instructions for Bean Stitch Freevintagecrochet has are the same as what I have in an ebook from a 1904 book, Utopia Yarn Book.
Which is found here (free), http://eastmanpublishing.com/library...chet_ebook.htm
It has a lot of old stitches. It's both knit and crochet.
I know from doing the Bean Stitch you can freely adjust how many loops you have on the hook to get puffier or less puffy beans. They still look like beans.
I think the key to the difference is how they are finished off. At least when I make beans I close them tight.
But I still don't really know why the Puff Stitches in the afghan at Freevintage look to be standing up, except if finished off like a DC would not pull them over like the Bean being finished with a chain.
I'd probably have to do it to understand it.
The pictures linked from How to Make also show the puff standing up.
I'm leery of sites that don't have them both figuring that somewhere along the way between "vintage" and now the two stitches have been confused and melded together.
I wonder why the Bean Stitch went away? I love the thing.
With a double strand and a huge hook it makes great hot pads. Single strand makes a cool border.
