I found this pattern for a Watermelon Coin Purse, but had some trouble with the directions in a few places and such. So I've translated it to American Crochet terms, Improved on places I didn't like and Added a few extra touches to make it look more polished.
I think this could easily be turned into a lemon, lime or orange (any round sliced fruit really) By just changing the yarn colors and instead of increasing in the Cream and Green rows, just Single Crochet across for each row.
1. In pink chain 3.
2. 3sc in 3rd chain from hook.
3. Chain 1, turn, 2sc in each stitch. (6 stitches total)
4. Ch1, turn, *2sc, sc
*repeat twice more. (9 stitches)
5. Ch1, turn, *2sc, sc, sc
*repeat twice more. (12 stitches)
6. Ch1, turn, *2sc, sc, sc, sc
*repeat twice more. (15 stitches)
7. Ch1, turn, *2sc, sc, sc, sc, sc
*repeat twice more. (18 stitches)
8. Continue in this way for 9 more rows – adding one extra sc between increases on each row. You should now have 45 stitches.
9. Ch1, turn, sc first 7 stitches, sc, dc next 14 stitches, sc, sc next 14 stitches, sc, sc final 7 stitches. (48 stitches total)
10. ch1, turn, sc first 8, 2sc, sc next 15, 2sc, sc next 15, 2sc, sc final 7. (51 stitches)
11. ch1, turn, sc first 8, 2sc, sc next 16, 2sc, sc next 16, 2sc, sc final 8. (54 stitches)
12. ch1, turn, sc first 9, 2sc, sc next 17, 2sc, sc next 17, 2sc, sc final 8. (57 stitches)
13. ch1, turn, sc first 9, 2sc, sc next 18, 2sc, sc next 18, 2sc, sc final 9. (60 stitches)
14. ch1, turn, sc first 10, 2sc, sc next 19, 2sc, sc next 19, 2sc, sc final 9. (63 stitches)

20. ch1, turn, sc first 12, 2sc, sc next 14, 2sc, sc next 13, 2sc, sc next 13, 2sc, sc next 14, 2sc, final 13.

Fasten off all colors.
Weave in all yarn tails.
For Seeds I used silver sequins that I just colored with a permanent marker. You can do the same, or use black sequins if you have some.
Other options could be small buttons, rhinestones, beads, or use black yarn to stitch on seeds.
Use black thread to sew on seeds, make sure to not sew any on the fold or too close to the edges.
Lay your watermelon on top of your lining fabric and trace around it. It doesn't have to be exact, just the basic shape.
Cut out the lining you just traced.
Iron on interfacing for added stability (option).
Fold lining in half, and cut down the straight edge. Now you have two smaller triangles.
With lining pieces right-sides-together, even out the rounded edge. You can lay a dinner plate on top and trace it or just eyeball it. Again it doesn't have to be exact, just make a smooth rounded edge.
Fold over the rounded edge of each triangle 1/2 inch. Fold the edge over towards the wrong side of the lining fabric. Pin as you go and iron.
Pin the underside of the zipper to the folder edge of the triangles. So that the right sides of the lining are facing each other.
Pin sides of triangles and sew.
If your zipper was longer than needed, go ahead and trim it here, to be the same length as the fabric.
Fold crochet piece in half, wrong sides together, and sew closed using same colored yard. Start from the pink and work up, switch color when you reach the next one.
Cut a 12 inch piece of ribbon and using a large needed thread it through two spaces between stitches on on the opposite side you just stitched close. Either tie the ribbon in a tight knot, or sew it together on the inside of the bag. About 1 inch from the ends.
Place lining inside the crochet to test out the fit. If your bag fits from side to side but is too deep/tall. Sew across the bottom about 1 inch, and trim the fabric. Then put it back in the crochet piece and test fit again. This did the trick for mine :)
If your lining is too wide and doesn't fit side to side, sew down the one side 1/4 - 1/2 inch, then trim and retest the fit.
Cut 2 pieces of 3 inch long ribbon, then if yours is a wide ribbon like mine, fold in half width-wise then fold it over the edges of the zipper. Then pin it in place and sew across it right below the zipper. Trim off the excess.
Place your lining back inside the crochet piece and pin it in place and hand sew either with matching thread so it doesn't show on the green, or sew it using an invisible seam.
If you don't know how to sew an invisible seam, here is a great link.
Make sure you sew back and forth a few times at each end to close up the sides where the meet.
Now you are all done!
You can add style and personality by attaching charms or beads to the zipper pull or the ribbon handle.
I hope you enjoy the pattern :D
