2. The previous quilts were all made up of quilt cover, quilt cover and cotton wool inside. It seems that young people nowadays don't use that kind of quilt very much. The outside is quilt cover, and the inside is cotton wool made of mesh cloth. If it is dirty, take off the quilt cover and wash it with the washing machine.
3. The quilt should have at least three layers of thickness, which are in the coldest winter, spring and autumn, early summer and early autumn. Ask your mother-in-law about the thickness of cotton sellers or cotton players. They all know it very well.
If you and your future husband are of standard figure, just buy a standard bed, generally 2 meters long and 1.5 meters wide. In the past, quilts were generally as big as beds, and each couple had a bed. Now they are all double quilts, usually 2 m 2*2 m 4.
You can take your husband to the store to buy a good quilt. Now the quilt can look good. Choose what you like, such as what season your wedding is, and buy a red quilt to celebrate. Others, such as early summer and early autumn, can buy something simple and generous. You have to buy it yourself. You may not like it if your mother-in-law buys whatever she chooses. When buying a quilt, give it to your mother-in-law and let her fill in cotton according to the size of the quilt.
Besides, you don't need to buy a duvet if it's not very cold. I heard that duvets are not as comfortable as cotton in hollow cotton.
Actually, I think your mother-in-law asked if you wanted a double bed or a single bed. Nowadays, young people usually get married with double quilts. Just go to the store and ask. Or you can ask your married friends of the same age. If you are old, ask your mother.
