Set myLabel = Application.MailingLabel _
.CustomLabels.Add(Name:="AdminAddress", DotMatrix:= False)
With myLabel
.Height = InchesToPoints(0.5)
.Width = InchesToPoints(1)

.VerticalPitch = InchesToPoints(0.5)
.NumberAcross = 4
.NumberDown = 20
.PageSize = wdCustomLabelLetter
.SideMargin = InchesToPoints(0.28)
.TopMargin = InchesToPoints(0.5)
