Is long stitch considered needlepoint or a type of embroidery?

Your answer is embroidery

Through the years, I've done a variety of needlework, and whenever I've seen the term 'long stitch' used to describe kits and projects, they've been what I would consider needlepoint - that is, they used needlepoint yarns and were done on needlepoint canvas. While 'long' stitches are common in traditional embroidery and crewel work, the technique is a little unusual in needlepoint so it seems to need a special name there.

The examples linked below are both from discussions of needlepoint rather than embroidery.

Like so many things, the truth may depend on context.

It depends on what you are putting the stitch in or on.

If you have needlepoint canvas, it is needlepoint.

If you have cloth, it is embroidery, perhaps crewel,m or perhaps just embroidery..

I went looking in my how to needlework book, both teach basic and fancy stitches, but neither needlepoint or the embroidery section mention a "long stitch" by that name. And I do both kinds of needlework, and did not know any stitches by that name.

So, my book calls it a straight stitch, and so do I.

And the two sources on line that have it refer to a longer stitch used to satin stitch embroidery, and in needlepoint as part of something else.

So, it depends on what kind of needlework you are using the stitch on, it depends on what source you are using on what to call it, depends on who taught you the stitch and what they called it.
