I wanted something special to finish off my 
Totoro in the Rain Afghan, and I thought of the acorn motif in the movie.  Inspired by Moogly's 
Polka Dot Border and the 
Cupcake Celebration Granny Square by Acorn Tree Creations, I created this Acorn Border.  Would you like to try it?  You'll need a crochet hook that matches your project, and yarn in:
- a background color (I used off-white)
- dark brown for the acorns
- tan for the acorn caps
I'll give you instructions with detailed pictures first, then the pattern all together. 
Begin with a row or two of sc in your background color.
Row 1: Sc, *ch3, 3 dc in side of sc just made  
(point made), 
skip 2 st, sc, 
ch 1, skip 1 st, sc*.  
Repeat instructions between *s.  
If you are crocheting around a corner, adjust so that the ch 1 stitch is directly over the center sc of the corner.
If you are crocheting all the way around a project, at the end of the first row ch 1, sl st to join first sc of the row, fasten off.
 Row 2:  Join dark brown with sl st in 3rd chain (top of a point), *4 tc in ch 1 space, 
sl st in top of next point*.  
Repeat between *s.
At the end of the round, sl st in first point, fasten off.
Row 3:  Join tan with sl st in 4th tc, ch 5.  *Dc 5 together in next 4 tc and sl st, ch 5*. 
 (To dc 5 together, *yo, insert hook in next st, pull up loop, yo and pull through two loops*, leave two loops on hook.  Repeat between *s until you have 6 loops on hook.  
 Yo, pull loop through all 6 loops.)
 Repeat between *s, join with sl st at end, fasten off.
At corner, increase ch before and after corner acorn to 7 ch.
 Row 4:  Join background color with sl st in top of acorn cap.     
 *4 dc in top of background point (over tan chain and dark brown sl st),
 sl st in top of acorn cap*.
 Repeat between *s.  At end of round, sl st in first acorn cap, fasten off.
 No adjustment should be necessary at corners.
The acorns should puff up from the background stitches. 
End with a row of sc in background color, and another row of sc in a contrast color, if you wish.  I used dark green to finish off the 
Totoro in the Rain Afghan.
