I'm going to put the individual tips in alphabetical order....my attempt at being logical!
Tips so far: A3, B2, B7, D5, F5, J5, L3, L13, M3

B-2, Sweet Tater Pie (from Susanne K.). 
Redraft onto freezer paper and convert the 2 piece sections into 3 piece sections.  Erase the corner miters.  Make two 4 patch blocks using 1/2 square triangles.  Reverse the colors in the second one.  Cut out a circle from the freezer paper for the center and applique onto of the larger 4 patch.  Cut away all the "4 patch sections" from the left over freezer paper so that you have a nice "frame". Reverse applique this over the 4 patches.  Yes, I have a diagram.  Let me know if you want it  :) 
 

B-7, World Series, works for A-3, Hunter's Moon (from Susanne K)
You need two pieces of colored fabric and background  for the melons. Trace your design onto freezer paper.  Cut out the  center star, the 4  melons and you'll have the circle in a square left  over. Iron the center star onto the right side of a piece of color fabric. Iron the melons onto the wrong side of the background.  Baste under one edge of  the melons.  The other raw edges will be covered  later. Using the center star for placement, applique the melons in  place, just the inner edge. 
Iron the circle in a square onto the wrong  side of a 5.5" square  of color fabric. Trim out the center of the circle,  baste under the edge. Place this over the melons, applique  in  place.  Ta Da!  No points  to do, not even on the melons. 

D-5, Cathedral Window (from Marsha)
I paper pieced this one in 7 sections. 
1) center square with it's 2 side borders 
2)& 3) the 2 remaining border pieced with corner units 
4)-7) the 4 outer corner units. 
Sew unit 1, add units 2&3.  Add 4 corner units, admire.

F-5 Parcheesi, no melon method (from Susanne K)
trace diagram onto freezer paper 
cut out  2 "red" sections only 
iron center "cross" onto back of color fabric, baste under edges. 
applique onto 5 inch square of background 
iron the other freezer paper template on to the back of color fabric 
trim out the center, baste under edges, reverse applique over the center 
or...

Looking at the block, visualize the center circle using the outside edges of the melons as a guide.  See the circle? Cut it out of the freezer paper, then cut out the center "cross".  Forget the 4 squares for a while. Follow direction form above, but instead reverse appliquéing the outer red section with squares, you will just be doing a circle.  Then when all is said and done, applique the 4 squares.
You may see another variation, if so, and you like it, go for it. 

J-5 John Jacob's Windmill (from Marsha)
I machine pieced, pp'd and appliqued this one. 
I machine pieced the center square unit with it's background border.  Next I pp'd the wedge units to the 4 outer border units.  I basted down the curved 
edge of the wedge units, before attaching them to the outer border pieces. This leaves you with an outer border "frame", which I carefully pinned to 
the center unit, butting the curved edge of the wedges to the corners of the center unit.  Hand appliqued the frame to the center, a flat block. 

L-3, Reflections Abound (from Susanne K)
....Make 2 four patch blocks, one for the center circle and another for the narrow ring. 

Applique the center circle onto top of the larger four patch.  Reverse applique the outer "frame".  Done.

L-13, Harvest Moon (from Susanne K)
Trace diagram onto freezer paper.  Cut out the circle for the center and a circle in a square for the outer section.  You'll have 3 sections. 
Make a 5 inch 4 patch and a 4 inch 4 patch. 
Iron the narrow ring onto the back of the large 4 patch, don't baste under the edges. 
Iron the center circle to the back of the smaller 4 patch, baste under the edge. Applique this to the larger 4 patch. 
Iron the circle in a square onto a 5.5 inch piece of background fabric.  Baste under the center edge.  Applique this over the 4 patch sections. 

M-3, Fireweed (from Susanne K)
I paper pieced this in four sections.  Quarter it right through the center with a "cross", not an "x" and eliminate the background square for the moment.  After fpp'ing, applique onto a background square.  I'll post the diagram at my web site later today.
