On the lightest piece of cardstock -draw a starting point. Make it big enough to see easily (you will be covering it over anyway with your card's main feature/stamped image so don't worry if it is a bit messy), I use pencil because it can be rubbed out later. Rule lines through the central point, I like to have about 12 pieces at the end of the day. So I obviously draw six lines through the central point.
I start by cutting the card at a half way mark (need not be perfectly in halves) ~ I am referring to the pieces here!
I cut each subsection of the pattern separately (in my mind I divide the segmented areas into four) and stick them down as I go. So above the cut pieces are piece #1 (on the top left hand side), the middle piece is actually piece #2 and #3 it just hasn't been cut yet and the one on the bottom right hand side is #4, #5 and #6 prior to cutting. . .
So here is #1, #2 and #3 ready to go.
I stick them down with snail adhesive and place each piece where it was in the original base card. And you continue to add the pieces. . .
So you get the idea. Make three base cards at the same time so that you are not left with odd shaped scraps and have three backgounds ready to go. You can adjust triangle sizes and the number of triangles in your background ~ you are only limited by your patience and your imagination. My thought is that they make great kids card bases.
Here is another that I made using a soon to be released stamp set ~ Animal Talk. Terrific when combined with the sound recording devices which will also be released in the new cattie.
