There's not much to these blankets yet there are endless possibilities depending on the fabric combinations, size, batting thickness and whether you want lace around the edge or not.
2 equal sized cuts of lightweight cotton fabric (a yard will make a rectangular blanket if the fabric is 45 inches wide so if you want a square blanket, ask for 45 inches. However, the size and shape is irrelevant to the construction as long as you have the appropriate lengths of material)
Lightweight batting, cut slightly smaller than the cotton fabric
Enough lace to trim the entire blanket and overlap slightly, optional
Coordinating cotton baby thread (it's yarn spun to a slightly thinner width than normal)
Embroidery or yarn needle
Snuggle!here for details. Good luck!
