    Wink Half rectangles help?

    Hi all...

    Trying to create a half rectangle within a half rectangle. Found a great website on how to do easy half rectangles (much like HSTs) here is the link if anyone would like it:
    http://themodernquiltguild.com/2012/...apes-tutorial/

    BUT... I want to add another isosceles triangle to one side of the rectangle. The finished piece would look like a rectangle divided in half diagonally, one side is a solid triangle, the other is a diagonal stripe and a smaller triangle finishing out the corner. These will all be chained together on the short sides so as to create a long border with a "tooth" look on both sides... finished rectangle size is 2x4.

    I can't figure out an easy way to make that smaller triangle without cutting individual ones. Any suggestions?

    Thanks in advance!

    So you want an isosceles right triangle in the corner?
    'Cause it HAS to be a right angle.

    The angle would be that of a HST rather the same one you used for the HRT.

    The first block below is an IRT. The other two are right triangles (half rectangle units) - you see the differences in the angle relative to the HRT diagonal.

    If you want the first one - the isosceles right triangle - the easiest way would be to just "snowball" the corner.

    For the square dimensions, just add .5" for the seam allowances to the side length you want.
    Place the square in the corner and sew ON the diagonal
    It's going to be a pretty small square so you really wouldn't have to bother marking the line.
    Check to make sure the angle is correct, and trim the excess off.


    If you want the (regular) right triangles (the 2nd and 3rd shapes), you can use the same method you used for the HRT, but with a smaller rectangle.
    At least you wouldn't have to deal with the exposed bias when sewing.

    Wow! What a great look those give! So many different ways to be used for patterns! Very glad you posted and got really a good lesson from MTS!

    By the way, you can 'snowball' with a more pointed look than a square gives you if you use a "kite" shape to snowball.

    Excellent MTS! THANKS! The middle one is exactly what I'm going for. Just stitching them together on the short side instead of the long. I was trying to figure out if there was a way to do two of these at the same time rather than each separately but I just don't think it's possible.

    BTW - what is "snowballing?" never heard that before. For the first quilt I made (See my avatar pic) the entire thing was HST and I used triangles on a roll... I literally could make a ton of them in a short amount of time and considering there were over 1000 in the quilt, I really needed the short cut. BUT would love to find other techniques as well for HST, HRT etc...

    Thanks again!
