The Olivia's Star is composed of 8 diamonds. By using the background fabric on each side of the strip sets, it makes these diamonds so dynamic!!
If your diamond is smaller than the template, here's a couple things to try:
Press, like really press! You will be amazed at how much you lose in seam allowance. I always take a scant 1/4" seam on bargello pieces and press my seams open. If you think of each seam, losing 1/16" in pressing to one side, that can add up quickly. Also, because this is a mini, it's much more important to have less in the seam allowance than showing on the right side of the piece. Trying to avoid sewing the seams into the next segment when sewing it together can be frustrating.
Trace the template onto the non-shiny side of freezer paper, using the 1/4" marking on the template. This will downsize your diamonds a little bit, but no one will notice! Cut the freezer template out and press it to your diamond. Mark as indicated, and use this as your new template. No problem!!
If your piecing of segments is a little wonky, bowing slightly:
Press, like really press! Nudge them back in line:) Lay your triangle on your piece and see if your slightly wonky piecing still can be trimmed off to fit the triangle. If so, start marking!! Because of the way it's pieced, with the background fabric making the bright colors seem to float, once these diamonds are sewn together, you will not see it, I promise!!
Next up, choose your setting fabric and let's put this together!!!
