Outlanding Stitch Compendium

Square 7 – The Duel introduced the new “Petranese” – the Black Sheep Crochet way of writing overlay crochet patterns. 

Squares 1 – 6 are currently updated from ‘OLD’ to ‘NEW’ Petranese. If you are not yet familiar with the new system or ‘Petranese’ in general, you can download your free copy of the Outlanding Stitch Compendium with explanations, instructions and photo tutorials for some special stitches here:

Alternatively, visit the online version (currently still a work in progress)

Skill Level

Wrapped in Jamie squares are designed in overlay crochet technique, which requires an understanding of basic crochet terminology and stitches. Most overlay crochet patterns are therefore by default classified as intermediate or even advanced. 

The Outlanding Stitch Compendium, however, has been created with an adventurous beginner in mind. It contains explanations for every aspect that is relevant in order to comprehend the patterns. (see above for download or website options)


Gauge is not important for these squares, but using the same yarn and tension for all squares and potentially the square border, big Claire square and triangles is. I recommend to make a small square swatches in your favourite yarn with different hooks to find the tension and drape you prefer. It may be a good idea to make a note of your final choice to keep with your project.

Here are some statistics for yarn I used to make the squares:

In one word: Hilarious. 

In three phrases: Petranese. Germanised British English. US crochet terms.

Seriously: US crochet terms

– When I started to read English crochet patterns, the first ones were written in US crochet terminology, which to me makes more sense than UK terminology (hence the US crochet terms) – no offence to UK terminology intended.  

– I live in Australia, where we speak and write in British English (hence the UK ‘colour’ or ‘favourite’ instead of the US ‘color’ or ‘favorite’ and the like).  

– My mother language is German (hence the Germanism including funny phrases, grammar and spelling mistakes)

– I could not find a way of easily describing stitch placements for overlay crochet special stitches, so I ‘invented’ a system. One of my facebook group members called it ‘Petranese‘.

There is no obligation to download the PDF version of the patterns. If you are a bit tech savvy or know someone who is, you can make a PDF from the pattern website.

However, if you like the patterns and want to support my design work or appreciate the patterns without ads to take along with you, there is an option to purchase the ad-free PDF version for each pattern for a small contribution through the shop. 


PDF purchases include the following bonuses:

  • a pattern booklet (5-6 pages for the written pattern only and 40+ pages for the photo tutorial)
  • my very own unofficial, hand ‘written’ design chart
  • Visuals for all rounds with special stitches / repeats or repeats within repeats / complicated rounds
  • Suggestions and photos for stitch marker placement
  • pattern as written pattern only AND detailed step-by-step, close-up photo tutorial pattern version

Direct links to the patterns are listed below.


The patterns are currently only available in “Germanised British English US crochet terms Petranese”.

There are plans to have the patterns translated into different languages once all WIJ patterns for the squares, square border, Claire, triangles and outer borders have been released.


You will also need

  • scissors
  • darning needle to weave in ends
  • stitch markers in different colours (optional, but highly recommended, this could even be a yarn scrap, a hair pin or a paperclip)


Breakdown of angular stitch abbreviations: 


type of stitch



st(s) ahead

= forward angular stitch


rounds below


treble 2 stitches ahead and 3 rounds below the next stitch = tr_+2-3


type of stitch



st(s) behind

= backward angular stitch


rounds below


treble 2 stitches behind and 3 rounds below the next stitch = tr_-2-3

Important Pattern Notes

  • For each special stitch you make in front, behind, around or in the front loop of another stitch from a previous round, you must leave the stitch behind or in front of the special stitch unworked (skip 1 stitch) unless instructed otherwise. The skipping of stitches will be mentioned in the photo tutorial, but not in the written pattern.
  • The ch1 at the beginning of the round does not count as a stitch and will be skipped when we slip stitch into the first sc at the end of each round.
  • Keep the slip stitch that closes the round loose as it will replace the sc below as the last stitch of the next round.
  • Visuals are read from right to left.
  • The use of stitch markers is optional and mainly intended to encourage and support less experienced crocheters. If finding free front loops is easy for you, you are likely to be quicker by crocheting without stitch markers.
  • If you follow the suggested stitch marker placements, take the st markers out of the stitch or front loop after the special stitches have been worked, unless instructed otherwise.
