'to add a sheet at the very beginning of the Sheets tab
Worksheets.Add Before:=Worksheets(1)

'to add a sheet at the very beginning of the Sheets tab
Dim shtLast As Worksheet
Set shtLast = .Worksheets(.Worksheets.Count)
Set shtNew = Worksheets.Add(After:=shtLast)

'to add multiple sheets before the active sheet
ThisWorkbook.Worksheets.Add Count:=<number of sheets you want to add>

'to add a new sheet before the current active sheet
Dim sht as Worksheet
Set sht = ThisWorkbook.Worksheets.Add
sht.Name = "<name of new worksheet>"
