The photograph above shows 4 ways of cutting and folding pieces of A4 to create different card bases. One piece of card is cut in half on the long side and the other on the short side. I used Rich Razzleberry.
Next take a neutral piece of A4 cardstock I used Whisper White.
On the short the short side this was cut at 19 cms. This piece was discarded. The remaining piece is then cut in half along the short side at 9.5 cms and then cut across at 6.5 cm intervals. You should end up with 8 pieces measuring 9.5 x 6.5.
Mount them as shown in the photograph.
These can then be added to the card bases.
