Dufex Pyramex Decoupage - Bygone Christmas. This sheet of Dufex Decoupage is printed on 190gsm high-grade Aluminium Foil Lined Paper. As with all Dufex products, the images reflect the light beautifully and shimmer as you change the angle you look at them from. Each piece is numbered for easy assembly. The sheet is Non-Die-Cut so it will require scissors (Fussy Cutting).
