Ahhh... should have thought Jelly Rolls, I just used that tube quilt pattern that brought me to this site.

when i was making clothes you used the edge but i agree with every one measure from the inside

If you are talking about precuts, measure them from the top of the "saw edge" on one side to the top on the other.

My pre cuts are 5" tip to tip. If I was to use the "dip" of the cut as the edge, that would make my finished block less than 4 1/2."

Also, I am curious as to how you would sew an accurate seam using the dip as the seams edge?

I'd found that the charm packs are not perfect and the pinked edges really suck when trying to line stuff up.

hmmmm i've sewn many charms together and use the pinked edge as the seam allowance with no problem.

YEP YEP! for precuts use the outside edge. I learned the hard way via a whole layer cake.

I don't like the pinked edge pre-cuts but have used some. I went by the top of the edge, don't know how the seams will hold up over time but .....

The jelly rolls that I have used are 2 1/2"...and to get the full width, I had to measure tip to tip...is that pretty standard then?

I use the tip of the pinking, not the valley. I've had no problems with the very slightly smaller seam allowance that results -- lots of wear and tear and washing, and no issues.

My only gripe with pinked fabric is the lint -- hate that.
