Sweet Home Collection Old World Style Floral Heavy Lace Kitchen Curtain, 36" Tier, Hopewell White

I've never known tiers to be 60" long, only panels! Are you sure that they aren't 36" long and 60" wide? Panels are long, and tiers are short.

Can you buy extra panels! I like mine full

Does this include the top and bottom shown in the picture?

Are these curtains made together or do I need a valance for middle
