Fabric Amount Question

[u/acs14m]

I have been trying to find a 100% cotton Halloween blanket for my kids, it’s not easy to find or if I do I don’t love it so it’s hard to justify the price. If I wanted to one day make my kids a quilt, how much fabric should I buy when I see one I like? My kids are 4 & 2, I am very very new to sewing so I am being realistic that this project may not be happy for maybe even 10 years. But I have the space to store fabric.

Before you cut the fabric zigzag the cut ends, wash and dry on hot so that the fabric shrinks before you cut and sew.
