I have the iron, cutting mat, cutting ruler, assorted sewing needles, assorted scissors and shears, seam gauge, tape measure, and seam ripper.
I also have a rotary cutter but found it not very useful. My pincushion is the traditional tomato kind; I don't like the magnetic ones. I do like glass-headed pins when I can get them, but couldn't swear to what kind I have currently. I use books for pattern weights.
What did they miss? Chalk. I have tailor's chalk and could not do without it. Carbon paper and a ballpoint tracer. Yardstick. Elephant tusk.
