Hi to the experts/developers

I have developed a routine to print slips, six to a (portrait) page (three
across and two down)
It works well. However when the pages are guillotined the slips need
sorting. When dealing wih a hundred or more the task is pretty onerous. I
wondered whether any one has had to deal with this problem before?

I would like to place them on the page so that when guillotined the slips
fall on top of each other in an easier-to-sort manner.

A partial extract from the routine:

Sub Numbers()
Dim myNumber As Integer
Dim Firstnumber As Integer
Dim LastNumber As Integer
Firstnumber = 1
LastNumber = 36
Sheets("Numbers").Select
Cells.Clear
For myNumber = Firstnumber To LastNumber
Cells(1 + (Abs(myNumber / 2 = myNumber \ 2)) * 10, 1 + (myNumber -
Firstnumber - _
(Abs(myNumber / 2 = myNumber \ 2))) * 2) = myNumber
Next myNumber
End Sub

This then lays them out as follows:
1 3 5 7 9 11 13 15 17

2 4 6 8 10 12 14 16 18

What I am looking for is something like:

1 7 13 2 8 14 3 9 15

19 25 31 20 26 32 21 27 33

Continuing to the right of the above
4 10 16 5 11 17 6 12 18

22 28 34 23 29 35 24 30 36
Etc

The maximum will be about 180 slips so they can go across the top but wouldn
't matter going down either.

Has anybody developed the maths to position the slips as above to facilitate
their guillotining?

Thanks
