Add flannel lining to crocheted blankets. I've never liked how airy crocheted blankets are - they let the cold air through (what's the point) and little fingers can get stuck. This is an option, though I would choose a different stitch pattern.
Versatile, simple patterns for scrap quilts can be hard to find, but this Scatter Sunshine Baby #Quilt is the perfect quilt #pattern for all of your smallest scraps. Intersperse strips of scraps with white strips to give this quilt a brighter feel.
