Yael, I used to cut my binding 2.5 and used the glue method with a 1/4" seam. I found I had a bit too much to turn over. Someone suggested cutting my strips down to 2.25, fold them before gluing. l like this much better. I have purchased a glue tip as I was getting too much glue while ironing and it made the seams hard as bricks to push the needle thru while sewing to the back side. I prefer hand sewing to the back as I can't sew a straight line if my life depended on it. I have also found that I can glue and iron the complete binding on in one step up to where I attach the ends together. Then I have to take it to the sewing machine to stitch the ends, then back to the ironing board to finish my glue process. Then I can stitch the entire binding in one swoop. I think the video showed doing one side at a time but I found that time comsuming. My miter corners come out great for me.
