### A Second Basic Vandyke Edge with Two Final Vandykes

Today's sample is similar to last weeks edge - there is only one square difference in the width of the border. This one has 10 squares in the border and 3 points on each side of the Vandykes and needs 2 Vandykes to create the last vertical edge.

First Vandyke with straight, vertical side
1 Net 2 knots in the foundation loop. (2 loops in the row)
2 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (3 loops in the row)
3 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (4 loops in the row)
4 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (5 loops in the row)
5 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (6 loops in the row)
6 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (7 loops in the row)
7 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (8 loops in the row)
8 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (9 loops in the row)
9 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (10 loops in the row)
10 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (11 loops in the row)
11 Net 1 knot in each loop. (11 loops in the row)
12 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (12 loops in the row)
13 Net 1 knot in each loop. (12 loops in the row)
14 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (13 loops in the row)
15 Net 1 knot in each loop. (13 loops in the row)
16 Net 1 knot in each loop except for the last loop, net 2 knots in the last loop. (14 loops in the row)
17 Net 1 knot in each loop for 11 loops; turn and net back across those loops. (11 loops in the row)

Repeating Vandyke
12-17 Repeat instructions to create new Vandyke.

Final Vandykes
1 Net 1 knot in each loop. (11 loops in the row)
2 Net 1 knot in each loop. (11 loops in the row)
3 Net 1 knot in each loop except the last 2 loops, net those 2 loops together. (10 loops in the row)
4 Net 1 knot in each loop. (10 loops in the row)
5 Net 1 knot in each loop except the last 2 loops, net those 2 loops together. (9 loops in the row)
6 Net 1 knot in each loop for 6 loops, turn the netting and begin the next row. (6 loops in the row)
7 Net 1 knot in each loop except the last 2 loops, net those 2 loops together. (5 loops in the row)
8 Net 1 knot in each loop. (5 loops in the row)
9 Net 1 knot in each loop except the last 2 loops, net those 2 loops together. (4 loops in the row)
10 Net 1 knot in each loop. (4 loops in the row)
11 Net 1 knot in each loop except the last 2 loops, net those 2 loops together. (3 loops in the row)

If you would like to know the math involved, here it is.

A. To find how many final Vandykes are needed:

1. If the number of squares in the border is less than or equal to 2 times the number of points -1 then you have just 1 final Vandyke.
2. If the number of squares in the border is greater than 2 times the number of points -1 then you need more than 1 final Vandyke.
(For this example: number of squares in the border 10 and number of points is 3, then 2 times 3 = 6, subtract 1 = 5. Since 10 is greater than 5 we will need more than 1 Vandyke.)

B. To determine how many more Vandykes are needed:
1. Subtract 2 times the number of points - 1 from the number of squares in the border (for this example 2 times 3 subtract 1 = 5)
2. Subtract that number from the number of rows in the border (for this example: 10-5 = 5)
3. Divide the result by 2 times the number of points. If the answer is not a whole number, round up to the next whole number. (for this example: 5 divided by 2 times 3 = 5 divided by 6 which equals .8333 or rounded up to 1)
4. The whole number is how many more Vandykes are needed. (for this example the answer is 1).
C. Total number of final Vandykes needed:
1. Take the number just calculated of how many more Vandykes are needed (for this example: 1).
2. Add 1 to that number to find the total number of final Vandykes (for this example  1 + 1 = 2).

D. To determine which of the 4 types of instructions to use for the final Vandykes:

1. Double the number of points along one side of the Vandyke (for this example the answer is 6).
2. Take the answer from B4 (for this example that answer is 1).
