I think Moda and the other companies stared out with 5" charms, but we quilters don't believe in rules and have kind of changed the rules...hehehe

So did I, and all have been so far except I have just received some which are 6" even better!

I'm with you I thought they were only 5"

I agree, I cut the larger sized charms because you can sub-cut them if you need to. I use the 5 & 6 inch charms.

I have been using 4" and 5" for 2 disappearing 9-patch quilts; I've seen them with 6", too large, loses its effectiveness
I use 2 1/2", 3" and 3 1/2" for other tops

My 1 1/2" day are over. I made my Postage Stamp years ago.
I sometimes do a checkerboard border with them though.

I'm using 6" and 8" squares to make 2 quilts with sports,animals and New England looking fabric for the 2 sons of neighbors who've been very kind and helpful to me. They'll be a surprise this winter.

Charms, by the way, have been around forever, long before Moda fabrics even existed.

Well then if that's the case about breaking rules then I like all the sizes. But I like the 5in most, I have to get a templet for that size.

It's very hard to find 5" templates in my experience.
I had a few made at my local glass shop. They made them in about 1/4" thickness of some kind of plastic.
If you go that route - tell them accuracy is critical.

Thank you for the info. I might try that if I can't find one with markings on it.

Me too.

I really like the 5". I also like the 10" layer cakes.
