Thanks !

I don't always use all of these. Only a few

I spot a Uni, a WD, a top ( a Topiary ), SF for superfood, RTH and fg, Ready to harvest and fully grown. SBL ... , FT seed but I would write Fairy Tale. A pink, is the diamond. AKP I use...  but write Red Squirrel.  Just don't want it to get too much. :) lol

Ty Tracey for the list!

This is MOST useful, though I will only remember a few. TY for all the work you have done on our behalf! You are kind!

            THX  for thanks is what i use a lot

Cham/Chammie - Chameleon (the latest slang word flying around Fairyland with the new release)

I sometimes use Cham when I am in a hurry.

I use WM for white mouse, FM for field mouse, duck for mallard and PM for pygmy mouse.

Thank you very much!
