But I only have shafts rising?

Good for both Spring 1 and Spring 2

If you have a narrow warp and have tied up only 4–6 shafts, it is completely normal that, when you release a treadle, your shafts may sink to their lowest position. In this case, all your warp threads begin from the bottom shed position—much like a jack loom. This is perfectly fine. If your tie-up is correct, pressing a treadle will raise only the upper shed.

However, if you have tied up additional treadles—even ones you are not using, such as a simple tabby tie-up—the resting position of your warp may shift higher. In that case, you will notice more balanced up-and-down movement with each treadle depression.

A different warp—wider, denser, or threaded on more shafts—will also produce a more typical countermarch appearance.
