TAST #113 is appropriately called Beaded Feathered Chain.
As usual I first tested it on Aida and then added it to my sampler.
Go to Pintangle to learn.
On the left, in the picture below, I made a 'back stitch' one hole above where the straight stitch was inserted to be able to anchor the Chain stitch.
Annet of Fat-Quarter has worked this and another version of the Feathered Chain on her blog. Check it out here.
