I have machine bound my quilts ever since I became the Project Linus coordinater for North Wales as the quilts get so much more wear, tear and laundering than a normal quilt, it can be easy once you have got the hang of it, but you must use the correct measurements.
My binding, for normal wadding, is 2 3/8"binding, folding in half longwise and stitched on with a 3/8" hem, when folded over the edges, back and front match EXACTLY. On my Elna 720 I have a blanket stitch but on the example below I used a stepped zig-zag as most of my pupil's machines have that stitch. The secret is to pin the binding in place 6" - 10" at time placing the pins in sideways so you can take them out easily as you sew. Don't be frightened of a machine sewed binding it is so much more durable for hard wearing quilts and if you use a variable thread it is stunning.
Hope this answers your query.
