How To Square Up A Half Square Triangle Quilting Block

This quilting technique from Quilting Blocks & Patterns on Youtube will help you, especially if you’re new to quilting. This tutorial will teach you two methods on how to square up a half-square triangle block. It’s quick, easy, and a clear method of how to do this properly. Watch the video tutorial below to learn.

Materials:

• Your quilt project
• ruler (with a 45-degree angle)
• straight ruler

Directions:

Method 1

For example, if you want to end up with a 6×6″ block, take your square ruler and line up the 45-degree angle mark on the seam line. Move the square ruler over, still keeping the 45 degrees on your seam line, leave some excess fabric, and trim up the side and the top. After this, turn it around (2 turns), then line up your 45-degree angle again on the seam line, and this time, you’re going to line up the 6″ line, (6″ line up, 6″ line along the bottom, and 6″ line up the side), making sure that you have your line on your seam.

Method 2

For the second method, grab your straight ruler and line it up on the 6″ mark. Line the edge of the ruler and make sure the mark that’s on the 6 actually lines up with the seam line. Do the same on the other end. So bring the edge of the ruler down until you see the 6″ mark and put it on the seam line. Now, cut the excess fabric. You have now a 6×6″ block.
