Crochet Stitch Bundle

Striking stitches crochet pattern bundle

This easy crochet stitch is part of the Striking Stitches CAL (crochet along). Join the fun and discover all-new crochet stitches here.

All stitch tutorials are available on our blogs but if you want a printable PDF version for easy recording and to take notes etc. You can grab the bundle with all 8 stitches here.

Sometimes it’s just easier to have a stitch dictionary on hand when you’re deciding on your next project rather than having to search online and remember where you saved that stitch you want to use.

Before You Start


  • 5 mm / US H – 8 hook. 
  • Worsted weight yarn. I used WeCrochet Dishie (worsted weight, 100% cotton, 174 m/190 yd, 100g/3.5 Oz) which has an amazing stitch definition which really helps when learning new stitches.
  • Tapestry needle to weave in the ends. I love this set as it has different eye sizes for different yarn thicknesses and it comes in a small tube which is very convenient so I don’t lose them.


The pattern is written for a 15cm by 15cm / 6” by 6” square.  You can easily adapt the size to your desired project size with the stitch multiple info below.

Stitch Multiple

The lace triangle crochet stitch pattern needs a multiple of 6 + 1 number of stitches; your starting chain will be a multiple of 6 + 3 for an extra turning chain.


The gauge for this pattern is 16.5 st by 15.5 rows in stitch pattern for a 10 cm by 10 cm square (4” by 4”).


This pattern uses US notations.

  • st = stitch
  • ch = chain
  • sc = single crochet
  • hdc = half double crochet
  • dc = double crochet
  • tr = treble crochet
  • yo = yarn over
  • fpdc = front post double crochet
  • bpdc = back post double crochet
  • skip = miss
  • sl st = slip stitch

Work instructions between [] the indicated number of times or until the end of the row.

The final number of stitches is indicated at the end of the row between < >.

The turning ch 1, ch 2, ch 3 don’t count as a stitch throughout the pattern except if mentioned otherwise.

Stitches above a ch-1 space are worked in the ch-1 space except if mentioned otherwise.

The pattern is written in crochet shorthand.  For example:

  • “sc 1” means to single crochet in the next stitch,
  • “sc 2” means to single crochet in each of the next 2 stitches,
  • and “2 sc” means to single crochet twice in the next st.

All pictures show lefthanded crochet. All stitches are symmetrical and can be worked by both right and lefthanded crocheters.
