I am starting my second quilt (first needs quilting as soon as I have the nerve to try it.) Anyway it was appliqued so no templates were used. On this next quilt the directions call for 1- 3" triangle template and 1-3" square template. I have a couple of question.

1. I know I need to add the 1/4 around or 1/2 " to two sides, of the square because I am going to piece by machine, can I also cut this square in half and end up the the right size3-1/4" on all three sides?

2. If I use a template (hate the marking-like rotary cutting) can I mark on one piece and cut with my rotary cutter through 4 layers of fabric?

What have some of you done and how has it work out for you?

Oh! if anyone would like to add some advice or their experiences on keeping points nice and sharp I'd appreciate that also.

shnnn

the squares you can certainly rotary cut... but, what kind of triangle is it? If it's a half square triangle it sounds like good math to me. But, if you are doing a whole bunch of half square triangles I wouldn't cut each individual pieces anyway, I'd speed piece them.

Does the block have a name? If it does try putting the name in a Google search and add rotary cutting and see if a tutorial comes up. Most simple squares and triangles can be rotary cut using your acrylic rulers. If they are half square triangles done in 2 colours, I like to do those as squares. I am not sure but I think it's 7/8 you add to a square if you are going to later cut it into two parts. You put your light square and your dark square, right sides together. You draw a line through the center of the square on the diagonal. You stitch a 1/4 inch seam on either side of the line and then cut them apart on the drawn line. You now have to triangle units. This may work with your pattern or it may be the wrong triangle. Good Luck.

I also would speed cut!!!!

I count the number of HSTs I need, count how many in each color combo...we'll say i need 100 for a whole quilt in black an white. I draw a grid on the back of the 'light' fabric...it could be 10 x 10, 2 x 50, 4 x 25, whatever fits (that equals 100) on my fabric because this is determined by the size of the square....

Now what do I need? Finished size = 3"... so I draw a 4" grid. You do not sew on these lines, they are cutting lines for later. Do NOT cut now! Draw one set of diagonal lines from corner to corner starting in the corner square and then moving to the next diagonal..all the way across the grid... You only do this one direction for HSTs. Pin the fabric together, avoiding diagonal lines and placing no more than 6" apart. Beginning in the center, sew a 1/4" seam on BOTH sides of the longest diagonal. Repeat in both directions from the center outward, sewing on both sides of ONLY the DIAGONALS. Press the entire grid so that your stitches are all set in one move.

Cutting: Cut the grid apart on EACH DIAGONAL line. Now cut each strip apart on the VERTICAL AND HORIZONTAL lines....you now have 100 seamed, pressed HSTs. Begin to open each folded square with the dark half on top. This will make it easier to press the seam to the dark side. I just open another square on top and shift it a bit, ironing both, over and over till I have 6 or 8, then move the stack and begin another. When all your pressing is done. Collect the squares, a work surface (kitchen cutting board works well), a small cutting mat and a 3.5" square ruler and rotary cutter. Put a chick-flick in the TV and begin to square up your little squares, matching your seam to the center diagonal line on the ruler. Cut 2 sides, turn 180 deg and trim the other 2 sides. you do NOT move ruler or square, rotate the small mat on the bread board... nothing moves or slips this way... line up right ON that bias seam and do not move... there will only be slivers, that's normal....

If you need an hourglass, the only difference is that you allow an extra 1/2", these would be 4.5" and then mark your grid with TWO diagonals. Everything else is the same till you get to the 'open and press' stage. Open, press and then flip to stitch the opposite diagonal line. It will only go halfway so you may want to draw the other half. If i have the first half, I feel secure enough to go across the other half with a mark on my sewing machine where the point of each square is lined up...Line on first half, follow point on the second half. Cut the cut the squares apart and do the whole open and press and square up, but this time match the center of the ruler to the 'center of the X.' You want the block to be symetrical...it has to be centered to achieve this. The only differences here are the extra 1/2", the 2 diagonals, matching the two squares together (be sure to match light to dark, on both sides), and then the second press, cut, open and square up after (not 2 square ups...only after the second half). When making a large number of squares, I put one extra line on the grid...that way, if I mess up a seam or the cutter slips, there are a few extra squares to fill in without any extra sewing.

Why do I allow the extra bit when drawing a grid? Because we do not think in 7/8" ... it is way faster to put that entire inch on the finished size, faster to draw and figure.... then I have a bit to square up and so each HST is perfect because it was squared up AFTER the sewing and pressing... if you make your HSTs with the 7/8" extra, you have to rely on perfect cutting, perfect sewing and non-stretching pressing to achieve this and it is difficult to measure and cut at the weird measurement. I am saving so much fabric with the grid method that the teeny bits I trim off are well worth it for the accuracy I get. Make a small sample, 2 squares x 2 squares... (2 x 2 = 4 to sew, but you will get 8 HSTs from this...as there are 2 HSTs per square, finished)

You might want to check how old your pattern or instructions are. If they're more than 15 years old, they will tell you all about templates. Newer patterns show rotary cutting instructions. Me? I rotary cut everything I can. My scissors are only for snipping!
