How to deal with the reverse side of patchwork quilt

I don't know which layer is the reverse side of the patchwork quilt you mentioned? As far as I know, after the splicing is completed, the reverse side of the patchwork will naturally be stitched with a layer of lining. As for the reverse side of the quilt, there are two ways to deal with it. The first is to sew a layer of cotton cloth directly. If you want to make a cold quilt in summer, the fabric can be thinner. If you want to make a quilt in winter, you can add a layer of inner cloth to make a quilt cover, which can be filled with thick and thin cotton wool. Then this patchwork quilt becomes a quilt cover, and you can keep your eyes all year round as long as you like.
