u/Glassy-Eyed-Quinn

I'm an amateur knitter and have made other projects but this is my first blanket. The blanket isn't ribbed however the border is a 1x1 rib and I'm wondering if it needs the extra effort of a tubular/stretchy bind off or if a regular bind off would be enough to not make a difference. Also should the back be lined with fabric as this is meant for a baby? If it matters, the yarn is acrylic for easy washing.
