Changes to some VB script which inserts WordArt

I have some code which inserts WordArt into excel.  I have tried to change the format of the wordart and it only applies to the first insertion.  I can see why it is doing that but do not know how to change it so that all the inserts are shaded...

I am really new to VB so any help would be much appreciated.
Thanks
 

For rw = 6 To ActiveSheet.UsedRange.Cells(ActiveSheet.UsedRange.Cells.Count).Row Step 20
            Set NewWordArt = ActiveSheet.Shapes.AddTextEffect( _
                PresetTextEffect:=msoTextEffect1, Text:="Generic", _
                FontName:="Arial Black", FontSize:=50, _
                FontBold:=msoFalse, FontItalic:=msoFalse, Left:=ActiveSheet.Range("B" & rw).Left, _
                Top:=ActiveSheet.Range("B" & rw).Top)
             
            With ActiveSheet.Shapes("WordArt 1").Select
                Selection.ShapeRange.Fill.Visible = msoTrue
                Selection.ShapeRange.Fill.Solid
                Selection.ShapeRange.Fill.ForeColor.SchemeColor = 22
                Selection.ShapeRange.Fill.Transparency = 0.6
                Selection.ShapeRange.Line.Weight = 0.25
                Selection.ShapeRange.Line.DashStyle = msoLineSolid
                Selection.ShapeRange.Line.Style = msoLineSingle
                Selection.ShapeRange.Line.Transparency = 1#
                Selection.ShapeRange.Line.Visible = msoTrue
                Selection.ShapeRange.Line.ForeColor.RGB = RGB(0, 0, 0)
                Selection.ShapeRange.Line.BackColor.RGB = RGB(255, 255, 255)
            End With
