Half Square Triangles

This week it's Amanda's AKA @metroquilter turn to show us her block.  I looooooove this block. Amanda uses a different method to my usual way for her HST's (Half Square Triangles) but I *think* I may be tempted to continue her way in the future.

Half Square Triangles

@Metroquilter

Those who follow me on Instagram know I love half square triangles. I’ve tried lots of methods over the years but the method I prefer is to chain piece my triangles and then trim to size. Other methods include a) foundation paper pieced -which I find accurate but fiddly b) piecing to size without trimming - never worked for me! c) 4 in 1 - lots of bias edges and still have to trim.

We are going to make four 2.5inch half square triangles, with the final piece being 4.5inch square.  

Requirements  :-

(4)  3 inch squares from your scraps 

Instructions :-

Step one: Place two squares right sides together. You will have two sets of two.  

Step two: Cut once from corner to corner on the diagonal. This will give you four sets of triangles.

(You may want to mix the triangles up to ensure all four of the finished half square triangles are different. Just remember that the triangles need to be right side together).

Step three: Chain piece the triangles, using a quarter inch seam allowance. Snip the threads between the triangles.

Step four: Press each of the seams to the dark side. You will now have four half square triangles ready for trimming.

Step 5: With your ruler align the 45 degree line with the diagonal of the block. Ensure that a 2.5 inch square can be made and trim the first two sides of the block.

Step 6: Turn the block 180 degrees and again with your ruler align the 45 degree line with the diagonal of the block. Keep the ruler square with the two sides you have already trimmed, and trim the remaining two sides to make a 2.5 inch square.

Step 7: Arrange your four trimmed blocks as desired into a square arrangement. 

Step 8: Sew the top two blocks together and the bottom two blocks together using a quarter inch seam. Press the top and bottom set in the opposite directions. Place the two sets of two blocks right side together, nesting the seam. Sew together using a quarter inch seam.  

Step 9: Press the seams and you’re finished. The finished block will be 4.5 inch square.

Thanks Amanda, it's easy to make these blocks larger or smaller, depending on the size of your first starting squares. I made mine in an autumnal colour scheme this time, no sparkle but it's lovely and bright.  Most of these scraps must be about 10 or 11 years old as they were given to me by a friend's husband when she passed away, they were quite *out there* for French fabrics back then and I'll always think of her when I look at this block.

Remember to post your pictures on Instagram with the #scrapbagsampler hashtag, we're all thrilled so many of you are joining in. There are some fantastic blocks being made.
