I'm wondering how everyone else lays out the triangles and square to make sure they're lined up and centred? Do you eyeball it or mark each centre?

Well the best thing to do is mark the Center. Depending on the project, sometimes I mark and sometime I eyeball it. :)

I finger press my pieces. I fold the square in half and finger press. Then I fold the triangle in half and finger press. Then I line up the "fold" lines and sew.

Yes, if I mark, it is usually by finger pressing the fold, sometimes I will put a tiny pencil mark in the seam line or even a pin depending on the situation

I also finger press each piece and then line them up by the creases

I always mark it.

I mark it. If I don't...none will be the same. :?

I use Fons and Porters triangle end trimmers, than I just line up the edges and have perfect blocks every time. Doesn't take any longer than finger pressing as I trim as I cut out the pieces :wink:

Thanks :-)

I have a whole lot to make up for the blue and yellow swap, and was wondering how everyone did it.

I've eyeballed it in the past, but it's not a good enough match.

i use these too. i find it to be the fastest method
