I would be more tempted to use a pinking blade made for rotary cutting for quilt blocks, you may get more accurate cuts than with scissors :D:D:D

I agree

I don't pink mine. To hard to match seams.

I don't pink, period. LOL

I've started pinking fabric before pre-washing and like that it doesn't fray. Also, if I end up using a different piece, the pinked edge will remind me that it's already washed.

I pink before I wash to prevent fraying, but that is it! Def. not to cut out my pieces.

If you are pinking, where is the edge of the piece when you put it through your machine? Is the cut notch part of the 1/4" or is that excess?

I use them to pink the cut edges of fabric before washing, and I use them to cut swatches of fabric for my quilt journal.

Pinking shears are not used in piecing quilts. Seams are sewn at 1/4 inch, the zig/zag when using pinking shears cuts into your seam allowance. Less fabric in the seam allowance will make the seams weak and will pull out after some use.
Rotory cutters are the best thing ever invented for quilters.
When using them with quilting rulers we can cut precise pieces.

The only time I pink the edges of my blocks is when I am doing applique. It keeps the edges from fraying so badly from all the handling while hand stitching. I cut the blocks larger than called for in the pattern and then cut them down to size after they are finished and ready to be put into the quilt.
