Abbreviations: modern US, UK, and antique

The same fabric, three vocabularies. This table is the Rosetta stone; it is also, line for line, what the Frogproof translator applies when you paste an old pattern.

ch ch ch, "make a chain of N" chain
sl st, ss sl st Sl. C., slip slip stitch
sc dc (!) Sg. C., s, "plain" single crochet
hdc htr (rare) half double
dc tr (!) D. C., d double crochet
tr dtr Tr. C., t, tc treble
dtr ttr D. Tr. double treble

FLO / BLO front/back loop (described in words) loop choice

The two traps

  1. UK shift: every UK stitch name is one step "taller" than the same US name. Check the pattern's origin before anything else.
  2. Very old "single crochet": in some pre-1900 books "single crochet" means the slip stitch. If a Victorian pattern's fabric seems impossibly dense, that is why.
