This post is a bit old but still thought I’d offer where I got my measuring spoons. Don’t know how to do a screen shot and post it here so I’ll just give the name. I got mine on amazon from POURfect. It is listed as a 13 piece measuring spoon set. Also a set by Maxi-Aids. Haven’t used my set yet but it has every measurement you’d want. Both my set and the Maxi-aids set have braille on them so obviously designed for low vision/blind people (hope I’m not using offensive terms) which I’m hoping means they are pretty accurate.
Smallest measurement is 1/64th and largest is 2 tbs. when searching amazon I put in “measuring spoons” and then add a fraction like 1/64 or 1/32 to it and then smaller spoons will come up.
