Scrap Bag Sampler week 4 - HSTs



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 sides 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.

I was lucky enough to have some Half square triangle units left over from the perfect HST BOM, so I used them to make this block. Cheating ? Definitely not, just using up my scraps. There are no rules in this sewalong:)
