I love my June Tailor slotted rulers. And also my 6-1/2 x 24 ruler. And my cordless iron. Olfa 60mm cutter is a must-have. Pointy bamboo stick, curvy little scissors, lots of little sharp seam rippers, pointy tweezers, Clover clips, Pinmoors, Elmer's glue, lint rollers, those clicky rolly chalk markers.....it just goes on!! I have a LOT of "must-have" tools!!
They ought to make sewing chests that look like pirate chests, because all this stuff is like treasure to me! LOL
