DYI Loom Kit + Extension Part 1

Trying a new product can be a learning experience.  It happened when I tried the DYI loom kit.  I also bought one extension.  This is the extension kit:

Here is the basic kit:

Looking at the loom and it's components, it is an ingenious system.  With the extensions part, projects can be longer and larger.  I like products that have a capacity to adapt to the projects.  Putting the base with the extension was easy.

I put the threads but was unsatisfied with the result.

I removed the threads and put some yarn instead.

It look better with the yarn.  The thread was looking too fine on the loom, as if twas too fragile.
