We knitters know, that finishing one project often means beginning another that is likely very similar to the one we've just completed - that familiar combination of knit and purl, rows or rounds, increasing and decreasing. Nevertheless, beginning and ending projects is always momentous and that final act of casting or binding off is another area that bears some careful consideration.
Like casting on, there are multiple ways of casting off - each with attributes suitable for particular garments, stitch types or decoration. If your pattern hasn't stipulated what type of cast off to use, it's worth having a few techniques in your Knitters Arsenal with which you are familiar enough to select and create the perfect edge.
The most common cast off is the Standard Knitted Cast Off which uses the knit 2 sts, pass the first st over the second method to securely fasten off all the live stitches. It's important to keep this final row fairly loose so that you don't end up with a tight, drawn-in edging that won't fit over a head, hand or ankle! It's difficult to say just how loose these stitches should be, but as you get more familiar with casting off you will get a 'feel' for it without casting off so loosely that you end up with a flared edge.
Standard Knitted Cast Off
Some knitters find that the Standard Cast Off really doesn't give enough elasticity to their finished edge and so the Decrease Cast Off is a great alternative - just as simple to execute but resulting in a much more stretchy edge. It's perfect for the top ribbed edge of socks, or roll neck sweaters, cuffs and ribbed welts. As an extra tip, if you know that you are a tight knitter and whatever type of cast off you use tends to be rather tight, then go up a couple of needle sizes - it will force more yarn into the stitches and so create a more elastic edge.
Decrease Cast Off
One of my favourite cast off methods is Elizabeth Zimmerman's Sewn Bind Off which creates a beautifully neat and stretchy edge that is incredibly versatile and can be used to finish almost any garment or accessory. I've found it particularly useful on the top edge of fingerless mitts as it gives just enough stretch to get them on, but is also nice and stable so that the edge holds its shape. This method uses a tapestry needle - as the name suggests, it is a sewn edge - but remember that you will need to cut your yarn at least 3 times the length of the edge you want to cast off.

As ever, there are many more cast off methods than I can mention here and it's worth doing some research to find some of the more obscure ones. Youtube will show you how to work a Tubular Bind Off to match your Tubular Cast On to create the ultimate, invisible professional edge, a Suspended Bind Off, various Picot Cast Offs to make the edge a little prettier or an Invisible Ribbed Bind Off as well as a plethora of others. Which one you choose, is up to you!
