Look for the needle's size number. All three types come in various numbered sizes. The higher the number, the finer the needle.
Match the needle to your thread size. The correct-size needle should be only slightly thicker at the eye than the thickness of your thread, making a hole in the fabric that the thread can pass through easily.
Match the needle to your fabric and embroidery technique. Sharp-tipped crewel or chenille needles work best for projects requiring you to stitch through the fabric. Blunt-tipped tapestry needles are suitable for stitches worked in the top threads of the fabric, such as in huck embroidery.
