need advice on setting blocks on point

Hello, I would like to make a quilt of 6" squares, (finished size) of each block, and set them on point. What size should I cut the triangles to make up the sides and four corners? Thank you, Barbara

the corner triangles are HSTs. the side triangles are QSTs.

usual formula applys. HST = finished size of square plus 7/8" aka 6 7/8". (corners) QST = finished size of square plus 1-1/4" aka 7 1/4" (sides)

for the HST cut two 6-7/8" squares (for the 4 corners), cut once on the diagonal, sew scant quarter inch seams. for the QST cut 7-1/4" squares, cut twice on the diagonals, sew scant quarter inch seams. how many you need will vary but you get 4 triangles per square.

if you're worried about accuracy at all, cut them a wee bit bigger. hope that helps, j.

You always were good with those maths!! I'm gonna put this in a file somewhere on the computer, because I know I'm gonna need it someday soon.

I'm coming up with a bit different answer.

If the blocks are 6.5" unfinished, then the diagonal of the square needs to be 13", plus interior seam allowance. Rounding up slightly, that gives me an

9.25" square, adding 3/4" for two diagonal seam allowances in the middle gives me 10". Since I'd rather have plenty and need to trim back a bit, I'm getting a 10.5" or 11" square cut into 4 pieces (an "x" type cut) for the setting triangles on the sides.

For the corner triangles, the diagonal needs to be 6.5" plus interior seam allowances. A 5.5" or 6" square cut on the diagonal will do the trick.

If in doubt, the easiest way is to lay the block down on point and place a ruler like the setting triangle would be. Add a couple of inches for fudge/trim factor, and you're good to go.

nope, i'm wrong it seems. brain is out action today. so delete that file, Jenn. i'm busy downloading Msg'r again. takes about an hour for this download on dial up. should be working again soon. will check for msg's and get back to ya, eh. :) jeanne

6 inch sqs on point still have 6 inch sides tho, no? isnt it like a sq in a sq. the side of the square (6 inch finished) on point is the same as the diagonal of the HST to add corners to it, no? and the diagonal of a sq is larger than its side, how big is the square you cut into HSTs? i wonder if either of us is correct now. hells bells i dont know at this point in time. i need a painkiller. j.

If the square finishes to 6", it has 6.5" sides unfinished, no matter what the set.

If you cut a right triangle so the hypotenuse is exactly 6.5", you won't be able to sew it to the 6.5" (unfinished) block, because when you go in a quarter inch for the seam, the line you're sewing on is now smaller than

6.5". In fact, it's 1/2" (2*1/4") smaller. I round it up to 3/4" and call it good, since I'm more willing to trim excess when I'm done than I am to run short.

And remember, most of the setting triangles (all except the four corners of the quilt, which are exactly like square in a square) will be QSTs, not HSTs, unless you love dealing with bias. So while the diagonal is longer than a side, you are only using half the diagonal.

Take the painkiller, have a good sleep, then cut out some pieces of paper and try it out. :)

as my brain is older than yours... i did not draw it out til just now and again got different numbers.

4 corners as HSTs... 2 to a square (cut once on the diagonal). those squares cut are smaller than the original 6 inch finished block as that is the diagonal side of the HST. i got 4-1/4" along the two sides, then added 7/8" (usual formula for making HSTs). i'd cut two squares (for the 4 corners) at 5-1/8" square.

the side settings as QSTs...

4 to a square (cut twice on the diagonal). long side of one of those i figure was 8.5" plus usual formula 1-1/4"(all seam allowances) for QSTs. i'd cut squares of 9-3/4", one square for each 4 side setting triangles.

to be safe on those scant 1/4" seams i'd upsize a wee bit and trim to the correct size. beats the heck out of me, j. be able to sew it to the 6.5" (unfinished) block, because when you go in a

Given the numbers you got, I know you used 6" for your starting point, not

6.5". :)

I used to do it that way, and learned from many bitter experiences to start from the *unfinished* size for setting triangles. :)
