Colour & Weave Gamp

The pattern is  featured in the  “Colour & Weave on Rigid Heddle Loom” course with Amanda Wood.

The pattern is intended to be used alongside the class. As I was learning to use this yarn I tried different setts and played with multiple ways of creating colour and weave effects.

For our gamp we are going to create 25 squares of pattern in one piece of cloth. From here we can plan any number of combinations in our next piece of weaving or we can choose to do another gamp that explores one pattern in multiple ways.

Tromp as writ is a weaving shorthand which means treadle as written. Treadling on the rigid heddle loom refers to the up/down position of the heddle and as written refers to the threading sequence. In this case it simply means we want to weave the weft colours in the same order as they are laid out in the warp.

Breakfast Eggs Towels Pattern

The first warp uses an easy all over houndstooth colour sequence leaving areas of solid yellow and white just like you would have in a fried egg and the second shows you how to use just a bit of striping to create a colour and weave highlight in the corner of your towels with a more muted scrambled egg palette where buttery and deep yellow combine. Mix and match and make them your own.

M & W Placemats Weaving Pattern

These 4-shaft Ms and Ws twill placemats are quick to weave up in 3/2 cotton. Weave a set of 4 matching placemats or weave one long table runner. By changing up your treadling progressions, you can weave a series of different twill patterns too!

Wall of Troy Runner Weaving Pattern

In The Intentional Weaver course with Laura Fry, we learned how to beam a warp using a trapeze and this is the project we put on the loom. It’s a 5-yard / 4.6 m long 3/2 cotton warp that we threaded on 8 shafts in a “wall of troy” threading pattern. This pattern can also be threaded on 4 shafts, so both drafts are included here. Changing the treadling will produce new patterns.

Scandinavian Sampler

Inspired by a rosepath pattern found in a vintage Swedish book of weaving designs. The sampler has a variety of motifs commonly found in krokbragd weaving. They are arranged in colorful bands with a broader field in the middle of the design.
