Creating your own stitch patterns (or modifying stitch patterns) is not difficult when using the Brother 970 and DAK.
Perhaps you see a stitch pattern in a magazine, you can enter the pattern directly to the 970 CB-1 computer, but the screen is quite small. It is much easier to create the stitch pattern in DAK, use a connecting cable and download it to the CB-1 box.
This tutorial will walk you through the basic steps. Included are common error messages.
