Then, when I went to put the blocks together, everything would be 'off' just that little bit. Now that I mostly chain piece (and pay more attention to the end of stitching), my blocks are much better.
Also, someone told me, once you've nested your seams, to pin at a 45 degree angle, rather than 90 degree and leave the pin in until the foot is just on it before removing. This has worked for me.
(I don't leave pins in any more - all I'm saying is - I'm glad I wear glasses for close work
)
Good luck!
this is my experience too. Also, in joining at cross seams, I make sure the top seam allowance reaches the needle before the cross seam, even if I need to clip the allowance to have it end up "to the dark". At a guild mass sewing event, I found that about 1/2 of my much more experienced guild sisters had troubles with ross seams.
