This design takes 32 minutes and 9 color changes. That 32 minutes is just sewing time, it doesn't include changing thread time and replacing the bobbin time.
The designs I use give suggestions for colors to use in the design but you can change them up to your liking.
Here is the paisley design I am making today nearly finished.
Trimmed and off the hoop. What a pretty tea towel it made. Down here in south Texas they call tea towels (cup towels), I had never heard them called that until I moved here.
