I have no idea of a "right way", but I'm thinking four triangles joined, then four more, then center seam, then add the white corners??? Any way you do it you'll have to twirl the seams at the joint and I'm not sure how that works either.

Sorry! no help at all

I get that I need to sew 4 center triangles together and then sew the other 4 center triangles together and that gives you 2 center "halves" that you then sew together making up the center circle of triangles. ........ I just have no idea when to sew the 4 white corner triangles on - either first ? or last? cause I am not sure how the seams would lay best...... that I don't want to figure out through trial and error as I would be ripping seams and I hate to rip seams. I hope someone can help me with this ....?? maybe Kate might know since she does all those medallion centers in her quilts?? Help please.

Best to you,
Sandra

Sew the triangles in sets of two. Join 2 sets to make a half. Join the 2 halves to make the octagon.

Then mark the center of your white triangle, and mark the center of your octagon triangle. Match those, then sew. I just use a finger pressed crease.

This method will likely correct any seam "wonkiness" you may have. If any seam is off by a bit, you may have a bit more or less of your white triangle points hanging off the edge, but the block should be pretty square.

Good luck! That's one of my favorite blocks.

Thank you Mary, I appreciate your help.

Thank you bunches,

I would sew the white triangles on last. I think the seam allowance should press towards the center.

Thank you all for your help and advice. Yesterday and just now I finished sewing all the center circles together. I just finished sewing the 4 corners on the first circle and it turned out really well, well had to rip seams a couple times, but it's finished and looks good now. Fixing to work on the next 4 blocks sewing the corners on. So thank ya'll bunches for all your help!

Best to you and thanks bunches,
