Well I saw a tip on Debbie Henderson's blog, and decided I could use it:
This is so easy, it's almost embarrassing. I took 4 pieces of 2" x 5" scraps (this is the Twinkle Twinkle Designer Series Paper) and cut them on the diagonal (place the short side at the top of your trimmer, and cut a diagonal from corner to corner). Then simply flip over one of the pieces, and now you have 8 different patterns.
I used a piece of 4" x 5-1/4" cardstock (a coordinating color - here, Night of Navy), and starting in the center, line up two of your triangles, leaving a small space between the pieces. The triangles will be larger than you need - that's fine; once adhered to your cardstock, simply turn over and trim off the "overhang". Continue adding your triangles around the cardstock until all the base is covered.
See the Silver Metallic Thread? And those stars are retired enamel shapes, but pulled together the papers and colors.
Here's another sample using the same technique but with Tranquil Textures DSP:
