I do what I call the baseball stitch it is the one they use to sew a baseball. This stitch is easier for me than the ladder stitch, I can go faster but at the sametime being carefull it is virtuely invisble. Another thing that makes stitchesivisible is how you cut your fleece. If the fleece is cut a little to small I have found that it has to stretch pulling at the seem making the stitch visible. but I have only been building puppets for two years so I'm not an expert. I'm sure I will learn a great more as I practice and thats the best trick practice, practice, practice!
