one thing about this- you say the (gift) is intended for a soon to be 1 year old.... she is going to love it whether it is wonky or not- so, don't beat yourself up too much and consider it a learning experience... a nice even straight stitch is generally what creates precise seams in a quilt- a serger is great for knit fabrics and garment sewing- but not so much when quilting. but, it will be fine. that baby is not going to care if the seams line up, she is going to love it because it is soft & cuddly and all hers- the fact that you did use the serger means it is going to be able to take lots of use/abuse- could wind up being that drag around, never leave home with out it blankie for her whole life (my youngest brother-in-law) still has 'pieces' of his favorite baby blanket tucked in a dresser drawer & he is 40-something) this could easily wind up *that blanket* ... so, continue on- learn some lessons- and know she is going to just love it-regardless of how well things line up.
