I think in the case of your crossed canoe block for the pieces that will end up being an outside edge it won't be too difficult. For basis of discussion I am looking at the upper left hand quadrant of the block. The two pieces that will be on your outside edge in that quadrant are the large white right angle triangles. Measure the distance from the top left hand corner over to the right where it switches color. Add your seam allowance and then another 1/2". I suspect the measurement will be 7" or very close to it in a 12" finished block. Now measure down to where it intersects with the "canoe". again, add your seam allowances and 1/2". I bet that measurement will come darn close to being 5". If you cut a rectangle to this measurement, on the grain, I bet you can make one diagonal cut from upper left corner to lower right corner and the resulting peices of fabric will be just right for PP the two white right angles in that quadrant of the block and also leave you outside edges on the grain, with just a bit left over to trim away.

Yes to what feline fanatic said about creating rt triangles out of recs, thus creating those straight grain edges......that was my thought too, and would do that if I were pp that block, but I would not pp that block, just piece it...

yes, I am aware that this technique was originally created to achieve nice sharp points out of complex shapes.....but I have also watched some demos where pieces were were just hacked to fit and sewed on, no concern about SOG....
So, I guess there are two sides to this coin.......

Fons and Porter sells an acrylic template set. You don't need to PP this block.

I also like tbe edges of my blocks to be on grain.

I took a photo of one quadrant of the block showing the edges are indeed on grain. I will finish the rest of the block and post again.

Ack! I have to change the tip!

Another reason to want to remain with SOG while PP ... some prints will be just awful if you slap-dash cut just any old way. Stripes going every which way on a block would drive me insane!!

If not for the print ... I personally don't worry about SOG on PP blocks, even large blocks. The reason is that I keep the paper on and then join the blocks. If the block is such that leaving the paper on makes joining the blocks a nightmare, then I'll baste the outside edge of the block to the paper along the seam line, then remove the paper, then join the pieces.

Mission accomplished!

Warbler, it looks like you've figured it out - nicely done! It really makes a difference since your fabric has such a directional fabric. Your quilt is going to look great!

Thank you Jennifer and everyone for the encouragement and great insight. I am fairly new to this forum but it feels like I have met a lot of kindred spirits who are skilled quilters and fun to be around.
