A choice of plain or patterned vellums, in a size that will run through your printer.
The heavier vellums can be embossed (if you are quick!) - choose the best quality print available on your printer and, having your embossing powder open and ready, sprinkle it on as soon as the paper emerges.
These A4 papers are also perfect for the smaller size albums that are around today - as well as cards!
