Wow what a brilliant thread! Loved reading through these (yep – another brush fetishist!) I’ve just been doing some more sketching whilst on holiday and had forgotten how much I love my Escoda travel brushes. I have the Optimo sable range in a 12, 10, 8, 6 and a Perla Synthetic sized 10. Really beautiful. I rarely use the 6, and usually find that the 12 and 10 are ideal for working A5 and A4. Had never heard of the Zechi brand before but shall definitely be checking them out! Oh, I keep my brushes tidy in an old leather cigar case (cheap on eBay) that has a lovely feel to it!
