3-1/8" Half Square Triangles

These 3-1/8 inch half-square triangles are cut with laser precision, so every single piece matches up perfectly when I sew them together. I got the windowed version, and being able to see my fabric through the hole saves so much time on alignment.

I was hesitant about paper piecing at first, but the pre-cut acrylic pieces save so much time. The seamed option makes alignment much easier for a beginner like me.

The windowed versions are a game changer for fussy cutting—I can see exactly where the fabric pattern lands before I stitch. The paper holds its shape through multiple passes without tearing, and the 3-1/8" finished size works perfectly for my scrappy quilt blocks.
