Warp Interlocking : Weaving Techniques
Posted on: 10 Jun, 2019


Warp and weft interlocking are techniques used for adding blocks of colors and creating seams of color. In these techniques, two weft yarns are woven or join with the warp yarns.

Weaving slits between color blocks is another weaving technique used to add colors side by side. This technique creates clear lines of division between the weft yarn and the warp yarns.

In this tutorial, you will learn the technique of warp interlocking. Warp interlocking joins 2 weft yarns in a row by wrapping the yarns around the same warp yarn.

To learn more how to use the other weaving techniques, check out these blog posts:

Warp Interlocking Tutorial

This tutorial starts with a triangle. If you would like to start with the same shape, or another shape, you can find a full tutorial here on this blog post Weaving Shapes on the Loom Guide.

Step 1: Weave a row of plain next to the the section you will interlock.

Step 2: Create an opening for the tapestry needle to enter with the yarn. The entry point should line up with each row.

Creating an opening:

Create the opening between two weft yarns on the same warp yarn. Do not weave more that one loop through the opening.

Step 3: Weave back a row and secure the weft yarn with a loom comb or fork.

Step 4: Start a new row and create an opening in the woven weft. Repeat steps 1 to 3.

Tip: Be sure to adjust the tension between the two weft yarns and the warp. Avoid pulling the warp too hard, so that it remains straight.  

Begin a new section by advancing the weft to the next warp yarn.

In this tutorial, you have learned the warp interlocking weaving technique.

There are various techniques to weave color and create compositions, so I encourage you to find the method that works for your weaving the best. This comes with time and practice.

I really like the zigzag pattern created with warp interlocking. This method keeps all yarns secure and the woven image in place. It takes time to get used to alternating between the rows of yarn, but with practice and time you can do it!

I hope this was helpful for you. Thank you for visiting my blog!
