Where can I buy a large, thick perforated felt area mat?

I literally spent hours and hours looking for the right mat, then spent hours looking for a 'make do' mat that didn't cost the earth. Still having no luck I had to again try and think outside the box.

This is when I dumped it in the Too Hard basket for months.

Project Redesign 3 : I bought a cheap area rug online thinking I could draw up a grid on the back and cross stitch it... so much more time consuming than it sounded in my head so...

Project Redesign 4 (final) : I found a very simple little cross stitch flower pattern in an image search and replicated it by cutting lengths of yarn and crochet looping each to match 1:1 of each X in the pattern and stitching them into place. So instead of my flowers being made up of X's, my flowers are made up of little tiny flowers.

I'm Very very happy with the almost finished rug. I'll post photos once finished.

Hope this clearly answers your question. I'm confused just writing it lol
