After my husband and I got engaged, we moved in together and combined our towel inventory. Obviously, this turns out to be quite an interesting combination. We don't have matching towels at all but I don't want to throw any of them away. We used to lived right by the beach so we have a lot of beach towels as well. Of course, beach towels are always bright and fun.
When we moved in our house in Hartsville, I realized we don't have a lot of storage space in our bathroom. After about 3 weeks of moving here, I realized I could utilize a rolling cart I had and put towels on there. It would also help guests know where to get them since they are on display. See picture below. I bought the rolling cart over a year and half ago for about $20.
