The Foundation Single Crochet (Fsc) is a great stitch to learn! If you don't like to start projects with a chain and then work into it, the Foundation Single Crochet is the solution!
The foundation single crochet allows you to work the chain and the first row of single crochets at the same time, which saves time and solves the tight chain problem!
Sometimes is hard to see the stitches of a chain, especially with furry yarns, with the Foundations Single Crochet you don't need to work into the chain!
Once you get the handle on it is a great stitch to have in your arsenal! =)
