what I do to get my seams to match is to put a pin in the seam of both patches then place a pin one on each side of the first pin about a 1/4 inch from each other this always makes the seams match. the nesting does not always work for me.

Good idea....sounds like you need a break! Things will be better tomorrow.

Get some of those fork pins at Joann's or any quilt shop - they work very well. I sew over them with the machine, but usually turn the wheel by hand when I get to the pins.
It goes right around the seam, one tine on each side of the seam.

My mother always stopped sewing and put everything away when things started going wrong.Saved alot of stress on her and us kids. HA!

I was just telling someone I'm in the mood to plan but not sew.I got the fabric and ideas but have to wait for the 'go for it ' time to happen. Reading your posts at this time I feel better about this. Like Kenny Rogers sang , " you got to know when to hold em you got to know when to fold em" cards and quilt pieces.
