I recently found a tutorial from Sally Pointer on looping around a core and really wanted to try it. I look some dried and rehydrated iris leaves from my garden, twined them, then started looping. I didn’t have enough material for a basket, but the thick twine did make a nice trivet.

I did overestimate the amount of core, but rather than cut it off, I switched to just looping with the tail and was able to add some width to the trivet. I then sewed a leather label in a circle to an outer loop.
I like this method of construction. The core gives a way to tighten the stitches and fill in the density of the looping. It can also be done as the twine is created and without tools, which makes it a great skill when I am waiting and don’t have a project with me.
