You will see crochet pattern instructions asking for the following 2 things:

  • Decrease Half Double Crochet (UK Decrease Half Treble Crochet)
  • Half Double Crochet 2 Together (UK Half Treble Crochet 2 together)

They mean the same thing; which is to reduce the number of Half Double crochet stitches (Treble Crochet) in your row or round by working 2 stitches together and decreasing the total stitch count.

Like other decrease stitches, half double crochet decrease is worked into the your previous row of stitches, across two neighbouring stitches. The HDc2tog works those 2 stitches together, so there is only 1 stitch above the 2 stitches of the previous row. 

The process of decreasing crochet stitches, is similar regardless of which stitch you are decreasing:

  • Start the 1st stitch
  • Leave it unfinished
  • Start the 2nd Stitch
  • Finish them together
