Are you sewing unironed fabric together ... did I read that right?
You'll find it much easier to get precise piecing if you iron and starch your yardage before you make any cuts. If you purchased 1 yard and you only need 1/2 yard - starch and iron 1/2 yard (and a few inches beyond) then start cutting.
After that, the only ironing (pressing actually) you should do after you sew pieces together is to press the seams (either open or to one side).
Especially important for triangles as all additional handling of the triangle can stretch the bias and throw the whole thing out of whack. I try not to iron my seams when working with tri's until I've sewn at least two seams of the tri (preferably the two bias seams) and even then ... you need to be careful not to stretch those seams when pressing the seams.
