I've never made a OBW and was eager to try. So I bought the F and P 60 degree ruler. Instead of cutting 6 identical layers I only cut 5. Not sure what I can do now. Any ideas??

Can you cut another layer, using the previous cuts as a pattern and match up pieces as you go? Definitely a hassle and not a quick and easy process, but it would enable you to have the proper pieces.

If you have enough fabric, put Glad Press and Seal on your ruler. Lay the ruler on a block and trace the features with a sharpie. You can then take your ruler to your piece and cut out an exact match for your 6th piece. Discard the plastic and put on a new piece, trace etc. until you have all your pieces.
If you don't have enough fabric, consider putting one solid shape in a the base kind of like the bird body of a peacock. The other 5 pieces will look like the tail and you could applique the eyes and beak on the plain piece? Just an idea.

I really like your idea, I might just do this on purpose to see what comes up. Thanks for the idea.

I took a class for the OBW through my quilt guild a few years ago. We only cut five on purpose, added a semicircle(base of the flower that the petals sit in) and then added the stem and leaves. Although I didn't care for the technique, it turned out kinda cute. OBW is definitely NOT for me...but then...that's why we are all "individuals"

Thanks for all the great ideas. I like the idea of making flowers since it is also a flowery fabric. I'll post a pic when I get it figured out. Even though i bought the fabric in the clearance bin, it is too pretty to give up on. Glenda
