If you feel more comfortable doing it, I would suggest that you do baste the edges of your quilt. Everyone here has done binding quite a few times. Hopefully, you have read some info about various techniques. There are so many ways of doing it. You really need to get the fold that is made in the corners as straight and accurate as possible. I have always done 2.25" cut strip double folded and hand stitched to the back. Good Luck !!
