2.  Join Color B.  Chain 3, 1 dc in same stitch.  1 dc in each of the next 5 stitches.  *2 dc in the next stitch, 1 dc in each of the following 5 stitches.  Repeat from *.  Join to top of chain 3 with a slip stitch. Fasten off Color B.

3.  To add the seeds, work with one strand of black.  Insert needle from the back and take a short stitch directly above it.  Reinsert needle in the same spot you came up in before and go down just to the left of your first stitch.  Repeat, going down just to the right of your first stitch. 

Repeat randomly around Color A until you have the amount of seeds you want.
 

4.  Using the pattern found here, cut 1 piece of insulating fabric.  Turn your potholder over and place the fabric on the bottom half.

5.  Fold the top down and pin into place.

6.  Edging:
Join Color C at one edge.  Chain 1, 1 half double crochet (hdc) and 1 dc in first stitch.
Single crochet (sc) in the next stitch.
*1 hdc, 3 dc, 1 hdc in the next stitch.  1 sc in each of the next two stitches.
Repeat from * around until you have 2 stitches left.  1 dc and 1hdc in that stitch.  21 shells, not counting the beginning and ending partial shells. 

If you don't want your edging to be extra frilly, you can do what I did.  After the 7th and 14th shells, make a decrease - when you finish your shell, put your hook into the next stitch as if you're going to make the sc, but don't.  With the yarn still on your hook, put the hook into the following stitch and make a single crochet, pulling through all the loops on your hook.

Loop:
Sc in the last stitch.  Chain 8 and slip stitch to the sc you just made. 
Turn, chain 1 and put 14 sc into the loop.
Join to the base of the sc and fasten off.

The finished potholder ....
