Estimate how much thread you need based on seam length, stitch type, and fabric layers.
Each stitch type uses a different amount of thread per inch of seam due to how the thread interlocks.
A standard bobbin holds approximately 60 yards of thread, though this varies by machine.
Always buy extra thread to account for thread tension adjustments, test stitches, and seam ripping.
