it depends on what you are doing with the quilt, utility quilts are probably fine being 'hemmed' but if you really want a nicely finished quilt to show off, the bindings are an important part of the finishing. it takes practice but each one you do will be easier and faster than the one before it and in no time you will amazed at how fast you can bind a quilt :)
when i first started it seemed like it took hours and hours...a week to do a queen size binding...now i whip them out in an afternoon...just takes practice.
