Spiraling regularity - AT174

The simplest designs can be so very effective, this straw place mat/table mat is an example of such a design. For Abstract Thursday with its optional theme of 'regular'. Don't forget to tag your entries with AT174 and do tell me if your correctly tagged entry doesn't show up in the whole AT174 collection, not even after an hour or so.

Thanks so much for your kind comments and stars for yesterday's mushroom cluster and for the ongoing comments, stars and hearts for the nautilus shell Blip. I've made another shot of the two halves with my phone today, showing the outside too, see the extra.
