Lily If you mean designs that are stamped (printed) onto fabric ready for you to embroider, I have done some stamped Cross Stitch designs in the past. I actually prefer it to counted cross stitch which I struggle to do now.
With cross stitch I have found that working each stitch individually (rather than working one way along a row stitching half of the stitch, and then back again doing the other half) gives a much better result and maintains the tension better. If you buy a kit they usually come with very detailed instructions and produces a nice finish.
Of course if that's not the kind of embroidery you mean, then ignore this!
