Brand new tutorials for PC-Designer by Angie Spong. Many of you will know of Angie from her website and may have some of her beautiful designs.

The first is a guide for beginners and introduces you to the PC-Designer program, right from the very beginning, getting to know the program, through to creating your own stitches.

The second is an exciting exploration of the M-Design section. Learn how to utilize the M-Design shortcut commands while working your way though the easy to follow, step by step illustrated exercises - combining stitch pattern sequences, letter sequences, multicolored pattern sequences and 9 stepping stitch maxi patterns using the 8 way feed. Plus - notes on creating your own stepping stitch sequences with Angies formula for using the Multi Directional Feed.
