Citrus Slices: 1) stem stitch an outer circle; 2) chain stitch just inside the stem stitch; 3) stem stitch 8-10 segments, evenly spaced in the circle; 4) starting from the point of each segment, stitch two long chains on the LHS, finishing just inside the top edge, repeat this on the RHS, then fill the middle with additional chain stitches; and 5) complete all the segments in the same manner. Note: that there are three tones of a single colour for each slice.
Just did this on a mug this week and love it! I do suggest baking it rather than letting it air dry. Be Warned--some sharpie markers change shades once baked. (ex. my pretty lime green changed to a darker forest green)
