Do you mean the binding??
Check out these tutorials I just sent to another quilter.
Here are some videos from youtube about binding. I use 2.5 " strips cut on bias. You can use straight of grain but I prefer bias.
This is a good video of applying the binding. But use the binding tool directions in this video with the tool. I find the binding tool much easier to use than trying to get the binding continuous this way.

Here is a video of hand sewing the binding down. (I do not iron binding in half. I roll it on a toilet paper roll)
