Well, that's my opinion. Other digitisers may make different choices. You can for instance reduce the stitch length, but I don't want that very short as the shine of the embroidery thread gets lost.

I've got a 6'4" fairy doing mine, but I have to clear up the stove and the counter tops afterwards :) And he ask if he was supposed to use that teatowel.

It seems such a waste to have an ever growing pile of try-outs!

My 4x4s were a bit less clear too, that's why I used the larger size. Have you used 5D (or 6D)? Double run or 4 double? I used 5D Stitch Creator first, with double run and stitch length 2.5, but was not too impressed with the result.
Then I used Embird, single stitch plus a backward path (which is comparable to 5D's double run) and stitch length 2.3, and even in the software I could see things I did not like in the 4x4 size. Hence the larger one. After stitching this teatowel I resized the one on the left till the heads were equal size - that stitches out well. Once I had my settings right I had a ball making the complete set.
