    I looked through the tutorial section but couldn't find an answer. If it's there, I'm sorry.

    My problem is a pattern I'm doing which calls for a ton of HST's. However, the pattern maker wants you to do it the hard way- sewing the triangles together instead of sewing squares and making them into HST's.

    I'm not good at math, so my question is, if the pattern calls for a 3 7/8" square to be cut into a triangle and THEN sewed into a HST, how much do I need to add so I can do it the easy way.

    Does this question make sense?

    The same size, just draw a diagonal line down, sew 1/4 in on either side, cut and press. you will get a 3" square with the two HST making the square.

    For me I find doing them the way you explained easier, but that is just me.

    Thanks for the answer! I like to do them that way because I'm more accurate at it than sewing the triangles together.

    I find the best way to do things is how it actually works out for you the best. there is so many ways to do everything, I am mostly self taught, I have done some reading and such.

    I find my HSTs are more accurate if I "round up". I would cut 4" squares, put them right sides together, draw the center line and sew 1/4 inch away on each side of the line. I cut them apart, press, and then trim to the correct size (whatever they were supposed to finish at in the first place). I just finished four blocks with 72 HSTs per block (I'm cross-eyed!!) and doing them larger and trimming they all fit together perfectly. Sure there's a small amount of wasted fabric, but that's worth it to me if my HSTs are accurate. Did this make sense? I know what I do but sometimes can't explain it well-sorry if I confused you more.

    That makes perfect sense! Thanks!

    This is exactly how I do mine, and I HATE trimming them but they always turn out so nice.
    I want to start on a quilt for my bed soon, it has 2704 1.5 inch HST in it! They all turn into 676 3 inch pinwheels. I get crossed eyed just thinking about it.

    This is what I always do also! Besides, it's easier to cut out 4" squares (for me) than it is 3 7/8" -- (where did that 7/8" mark go??? :shock: ) :D

    There is another way to do multiple hst at one time- I don't remember what site I got this off of, hope this helps

    Two Large Rectangles = Multiple Triangles

    Using this method, you will cut large, but manageable rectangles, mark sewing and cutting lines, sew them, and then cut the triangles. The preparation/marking time is less than if you were marking each square separately. The sewing time also is less since there is only one unit of fabric to handle instead of individual triangles.
    Step 1 – Determine how large to cut the rectangle pieces of fabric. To determine the cut size, take the finished size and add ⅞” to both sides. For example, if you are using 2” squares (finished size), the cut size will be 2⅞” square.
    Figure out how many of these squares you would like to have on your fabric. Using the above example, 6 squares across would require a 17Ό” length, and 4 squares down would require a 11Ό” width of fabric. This configuration would result in 24 squares of half-square triangles. You may wish to add extra on each of the sides.
    Step 2 – On the wrong side of the lighter fabric, draw the cutting lines of your squares. Using the same example, mark 24 squares that measure 2⅞ ” each. Then draw a diagonal line through the center of each square. This, too, is a cutting line.
    Step 3 – Place the fabric right sides together (one marked and the other one not marked). Sew each of the squares two times, Ό” on each side of the diagonal line through the center of the square.
    Step 4 – Press the sewn rectangle to set the stitching. Cut on the drawn lines to make your triangles.
    First, cut the lines to make strips.
    Once you have strips, cut them apart into squares.

    My brain does not do 8ths. I round up, sew and trim. It takes me longer than most people, but it's the only way I get it right.

    Look at the bottom of the page here
    http://www.bellaonline.com/articles/art10208.asp
    for grids you can print out when you need lots of them the same size


    I have some others bookmarked, just can't find them now.

    I also get much better results when I trim down the squares. I have discovered the cutting mat that rotates which makes that step faster.

    I'm also of the round up and trim down persuasion. I am working on Friendship Stars for two of the nieces and found that I could get better finished squares by doing it this way. I figured I was just an amateur hack, but I'm glad to see that some of you more experienced quilters do it this way too. I briefly considered that I was wasting fabric, but I figured the price was worth getting accurate blocks. The first couple that I did were nightmares b/c the sizes weren't exactly right, but the stars look great now. Maybe someday I'll get more accurate, but for now I'm perfectly fine doing it this way.

    El Burns has the best method for oversized then trimmed.
    She uses large squares that make 8 HST at one time.
    To trim to size takes one cut with her square up ruler.
    It is so easy and fast and the ruler comes with a chart for all sizes.

    I always add the extra 1/8" to make sure I don't have my HST too small. So a 4" square,mark the middle and sew 1/4" down both sides-cut apart on the marked line.

    If I were making that many small hst I would use thangles-just make sure you get the right size ones for the FINISHED size you need.

    Hi, when I made any HST's I always round up to the next number, in this case I'd cut 4" squares. Mark diagional, sew on either side of the line with a skinny 1/4", cut, press and then square up to size, in this case it would be 3 1/2". This way you are sure you HST is going to be the right size and the rest of the block will go together so much easier. You do the same thing with QST, round it up so when you get it made you can square it up to the correct size. :D Hope this helps and happy quilting. Jan

    I like to make 8 HST at a time. The only drawback to this method is that they will all be identical. Here is my formula:

    Half Square Triangles cutting 8 at a time
    Use two same-size squares to make multiple triangle-squares.)

    To determine what size squares you need to cut, multiply the desired finished size of the triangle-square by two, then add 1 Ύ “. For example, for a finished triangle-square that is 2 ½”square, use 6 Ύ” 2 X 2 ½ (finished size) = 5”
    5” + 1 Ύ” = 6 Ύ” square
    Bisect the square in half in both directions with a pencil and a ruler and then draw the diagonals. Sew 1/4 inch on either side of the diagonal lines and cut apart on the vertical and horizontal lines. You will have 8 half square triangles.

    i am with JanRN, 4" blocks is so much simpler.
    Or you could always use "thangles".
    .. and there are free print outs you can get on line too. I am not sure if i can post links..i will wait for an answer before i post them...

    I also use a rotating mat when cutting and marking smaller pieces....I made my own ! Just buy a lazy susan ( mine is wood--got it at a Big Lots store for $7) and attach a small cutting mat to the top...much less expensive than buying the "REAL" thing!
