Nellie Snellen 3D embossing folder Background Flowers 2. This is an A6 or 10.5cm x 14.8cm embossing folder that will create a raised design on card, vellum, foil etc. The 3d effect is created by the raised design being at different levels. This design has a repeating pattern with stylised flowers within a dotted framework, and would create a perfect background design for hand made cards for all types of occasions.
