The nice thing about vintage tea and kitchen towels are there also made of much better fabric and then you find and a lot of kitchen towels and tea towels today. The ones I look for are either a heavy linen or cotton. You will find some cute ones embroidered on what was feed sack material.
For the most part I hand wash them and line dry them, especially if they are embroidered. Sometimes I iron them before I put them out, or as was the case yesterday I just put them out.
You can find these towels in lots of places. Usually anywhere from $6 to $10 a towel. And those prices are pretty good considering a lot of them are all hand embroidered. And yes you can use them every day even with the hand embroidery! After all, they were meant to be used!
