Pity the folks who embroider on cloth. Most of the time they struggle with sharp needles with small eyes. While the sharp part is necessary for embroidery on fabric, those small eyes can be rough on threads.
Often the needles are difficult to thread and more delicate threads can shred at the needle’s eye.
For these stitchers the solution is a chenille needle. You can just think of them as tapestry needles with sharp points. For needlepoint you would use these if you were using waste canvas and doing needlepoint on cloth. You’d also use them if you needed to pierce the canvas threads as you stitch.
Switching to larger needles. even just one size up, may be the answer to many problems you have with thread.
