This is an original pattern of Karen's, called Summer Stars.

 

Prepare and mark a regular C10 on a 34 cm ball. Add additional mark lines to make a smaller pentagon inside each large one as shown in blue on the diagram. Work a small pentagon in each pentagon as shown in the red shaded area (approx 6 rows). Use the opposite marker threads so the points of the small pent point to the flat side of the "blue" pentagons. Work a star from points 1-3-5-2-4-1 beginning the points of the star 1 cm from the corner of the "blue" pentagon (shown as the black "o"). Make sure the first thread of the star lies flat against the flat side of the small pent made in step 2 (if not, enlarge or decrease size of small pent). Work six rows, then outline with one row metallic (shown in red on diagram). Work a large pentagon on same points as small pent in step 2, outline with one row metallic (shown in green on diagram). Work 2 rows just outside each original pentagon. Work small triangle on the alternate threads in the triangle where points of pents made in step 5 meet. Ball is complete.
