I'm a self-taught quilter which means I did what was easiest at the time. My first book actually called for 1/2" seam allowances. (This was in the dark ages--1975 I think!!) As I've quilted more and instruction books consistently called for 1/4" seams I've had to "unlearn" a lot. Try to "learn right" from the beginning. The more you do something, the more it becomes a habit--good or bad. As with anything new, practice practice practice. But practice the correct way.
Again, it's your quilt and the quilt police aren't watching.
I hope this made sense--I just wanted to help you learn from my experience ( or inexperience at the time)
Good luck and keep on quiltin'-
