Hey guys, i'm just wondering if someone has dimensions for me, it would sure help. Otherwise i can make my triangles bigger than necessary, then trim then back. What i'm wondering is this. I'm trying to make a quilt, with 10" blocks, set on point. So the blocks are 10 1/2"s, unfinished. And so, for the outher edge, i want to set in triangles. So what i'm wondering is, i want to take a square block, and slice it corner to corner, to make my triangles. What size block should i use to slice my triangles? Any ideas? :)

Here's a good chart to use.

cut your squares 10-7/8", then slice them on the diagonal as you planned.

Oh thank you Patrice, the chart was nice, but i was having trouble with the math. Will show you guys in few days what im working on :) Good deal, thanks! :)

This will work, but your bias will be on the edge of the quilt. If you want to put the bias on the inside, cut them 15 3/8 and slice on BOTH diagonals. This will make 4 setting triangles.

Don't forget that there is a difference between the CORNER setting triangles and the SIDE setting triangles.

Thanks Patrice and Dunster. hmmm, never thought about the bias, but now that i think about it, i think i'd rather deal with just one bias edge than two, so maybe i will machine baste my bias edge to stabilize it, maybe? lol :)

I'd just starch the fabric heavily before cutting. That will stabilize the bias edges.

oh i've never done starch...don't have any lol :) But that's a good idea

I love the mary ellen best press. Many quilter's have fallen in love with it for this reason.
