I prefer not to piece borders unless I have to, but I only make child size to twin quilts. I do usually make bias binding. Lots of good advice has been posted, and some great links. I've rarely run into anyone cutting fabrics at JoAnn's who sews, and many who don't have a clue about cutting fabric or panels accurately. I shop there for sales and novelty fabrics. I usually ask for about 1/4 yard more than I need since I prewash and many fabrics are wonky or cut a bit wonky even though I try to gently educate the cutter. I do commend JoAnns on their policy of selling the rest of the bolt IF it is under a yard for 50% off the current price as they would a remnant. A wonderful woman behind the counter told me about this a few years ago after she asked me what I was making and I told her donation children's quilts. Apparently most of the staff don't know this- you have to ask. I search for a bolt that is on sale and almost gone, then order an amount which will leave less than a yard if cut so I can use this to stretch my meager funds.
