We've had requests to support two sets of lease sticks with our Helping Hands product. This is useful when there are many color changes or when the weaver wants the freedom to "design color" while warping, choosing from two warps.
We've just developed this for the Spring II loom. If you would like to see this on another loom, please let us know so we can prioritize our development queue!
See the pictures on the product listing for this add-on to the Spring II Helping Hands for a visual of how this works!
