I stumbled on this post for making custom tea towels a while ago, and left it languishing in my bookmarks until I started thinking about what I wanted to make for Christmas gifts.
I used her guidelines for sizing and fabric, but decided that I wanted to design something instead of using recipes.
I designed a repeatable "tile" in Illustrator and uploaded it to Spoonflower, chose the cotton/linen blend fabric and waited!
Once I received the fabric, I cut the yard into four equal rectangles, finished the edges and added cotton tape on opposite corners for hanging. I did NOT wash the fabric before sewing (which I would usually do) as it's been my experience that the process of washing and drying can warp the pattern a bit on Spoonflower fabrics, and I wanted the pattern to be even and the towels looked crisper for gift giving.
