A design created in Not So Rigid Designer using 2 heddles, 2 pick up sticks, and color effects, in white and teal

Design with multiple heddles and pick up sticks!​

Not So Rigid Designer lets you make designs with up to 3 heddles and 10 pick up sticks!

This design has 2 heddles - the rows with circles (holes) and squares (slots), and 2 pick up sticks, which let you manipulate the slot threads. The weaving sequence is on the right - put the heddle up when the arrow is up, down when it's down, and neutral when it's a -, and use the pick up stick when it's mentioned.

Get beyond 1 thread in each hole and slot!​

Not So Rigid Designer makes it easy to experiment with different threadings, in combination with pick up, multipe heddles, and color and weave!

Quickly sketch out your ideas in your browser and sample the best ones!
