I just finished 2 crib quilts for great nephew twins. I cut both out at the same time. I pieced both at the same time; however, I sandwiched, quilted and put borders on as separate quilts. Since these were my very first quilts, I learned from the first one. I think if I had completed one and then started the other, I would have been bored and have wished I was done. This way, I was excited as I saw how each one was progressing.
