What are HST quilt blocks?
If you’re new to the term HST, they’re essentially square block units sliced diagonally in half and later sewn together with other pieces of fabric along their diagonal side. This then creates a crisp triangle formation on one-half of the new square block. Pretty easy, right?
There are various methods out there on the Internet that will guide you to making your very own HST quilt blocks. However, we’ve also taken the liberty to include some of the easiest ways to save your time! Just head on over to the frequently asked questions below that will guide you through all the juicy details.
FAQs Regarding Half Square Triangle Quilts
1. What supplies do I need to make HST quilts?
Before getting started on your quilts, you’ll first have to determine the essential supplies needed. These items can easily be purchased at your local craft stores or online. Here is precisely what you’ll need to prepare, but remember to refer back to your chosen patterns for the exact requirements.
– Quilting grade cotton fabric
– Batting and backing fabric
– Rotary cutter
– Scissors
– Quilter’s ruler
– Sewing machine and thread
– Cutting mat
– Quilting pins
– Iron and ironing board
– Fabric markers (optional)
2. What are the methods of making half square triangles?
There are several ways that you can prepare your HST blocks. These are the 5 common methods:
1. 2-at-a-time HST method: This is the most common method. Ideal for stash-busters and making blocks from different fabric combos.
2. 4-at-a-time HST method: This method uses larger starting squares to create four blocks at a time. However, it is not as perfect due to the biased grainline edges of the block, which may cause stretching and distortion.
3. Magic 8 HST method: This is similar to the bulk HST method but uses square fabric to produce eight blocks at a time.
4. Strip piecing HST method: This uses pre-cut fabric strips (e.g., Jelly Roll) to make the blocks. It also creates biased grainline edges like the 4-at-a-time HST Method, which are less perfect.
5. Easiest Bulk HST Method: This is the fastest and easiest method of making bulk HST quilt blocks. It provides a diagram to make a shortcut and repeated 2-color HSTs.
3. How do I make the correct sizes of my HST blocks?
Achieving the correct size for your Half-Square Triangle (HST) blocks is essential for precise quilting. The size of your HST blocks will depend on your specific pattern and design.
To simplify the calculation process, here is a comprehensive tutorial complete with HST charts that detail the initial fabric square sizes needed for the 2, 4, and 8 HST methods.
If you’re using random scrap fabrics and need to cut them to the correct size afterward, this tutorial also demonstrates how to utilize a square-up ruler for a quick and efficient shortcut.
4. Can I mix HST blocks with other quilt blocks?
Adding HST with other quilt blocks certainly creates a visually appealing and interesting design for your quilts. They usually pair well with squares, rectangles, and other triangle-based blocks. They also add variety to your quilt design and are a great way of customizing your quilts!
In fact, some of the patterns we’ve included in the list involve a combination of square and rectangle blocks. For instance, the Layer Cake Shake Shortcut Quilt, Five Patch Star Quilt, and Easy Spool Quilt Pattern. If you’re an experienced quilter and this isn’t your first rodeo, feel free to mix and match the blocks from several patterns to create a one-of-a-kind quilt.
5. What is the best way to press the seams on HST blocks?
Pressing the seams correctly can be tricky for first-time quilters. And sometimes, even seasoned pros make mistakes here and there if not careful. The best way to do it is relatively simple. With just an iron and your ironing board, you’ll be able to press your seams flawlessly, and here’s how you can do it:
1. Flip open your HST quilt block and lay it flat on any surface. Be sure to press the ¼” seam allowance at the back of your block toward the darker fabric. This helps to prevent the darker-colored seam from showing through the light-colored fabric.
2. Now that it’s laid flat, grab your iron and gently iron the front of the block. Make sure that your iron is hot enough.
3. Let your fabric cool, and you’ll have the perfectly pressed seam HSTs.
