How to create a crochet pattern – Part three



In the last two parts we talked about first steps, getting into measurements and writing out the pattern. If you missed them, please check them out here:

Today I want to talk to you about sizing and assembly. Once you begin creating your pieces you’ll need to monitor them as you go to make sure they are meeting the gauge size necessary to stay on track with your sizing. If you’re making a scarf or blanket knowing the gauge isn’t as pertinent as when you’re creating a garment that will need to be worn. Keep in mind also that making it slightly bigger is better than smaller since bigger can always be sized down, however, smaller is more difficult to adjust.


Schematics are basic shape renderings that show the measurement of each piece. Once you’ve completed your crochet pattern it’s a good idea to have sizing and shape shown in the form of schematics because then the reader can see and measure accurately what their piece should look like. Schematics do not take any fancy drawing skills. If you can create shapes in PowerPoint or a word processing software, you can create easy schematics to add to your pattern instructions.


Once you create your basic prototype you have everything you need to know how to adjust sizing. Having measured the gauge on your pieces and ensuring they are all the right size, you can now write adjustments for various sizes based on the prototype gauge. My suggestion is to again refer to the sizing chart you chose to use (here’s one: and find out how different the measurements are for each size. That way you can easily add the number of rows and stitches necessary to create larger or smaller sizes as needed.

After all the pieces are made, make sure to write out your specific instructions on how to do the assembly on each piece. If you need the reader to start at the bottom back corner so they end up a certain way by the end, make sure to write it down. So again, I encourage you to write or record what you’re doing as you go so no steps are missed and so that you can also know if anything needs to be adjusted once you’re done with the assembly. Once assembly is done, block the piece if needed making sure the measurements are still relevant to your sizing. Remember I said to block your swatch if you yarn needed blocking then to take the measurements so that you would be sure to have the right number of stitches done by the end of your project.


Something that will greatly help your crochet pattern reader is the addition of notes in your pattern. You can put the notes at the end of each section, which I suggest, or at the end of the pattern. However you decide to do it having notes gives you the opportunity to give added instruction to the reader on the crochet pattern they are working on. It’s a great way to anticipate and answer questions you think they may have and give them the answers. Putting in detailed notes is a great way to add value to the crochet pattern  you’ve written and give the reader confidence that they can create what you’ve set before them.



That’s it! You’ve just written your first pattern and it should have all the following elements:

  • List of materials
  • Stitch explanations if needed
  • Schematics
  • Gauge information
  • Detailed instructions on creating and assembling pieces

Once you create on pattern you’ll find it easier to create others because you’ll begin to get the hang of sizing, selecting stitches and gauging. Like anything, if you practice you’ll become very good at creating your own crochet patterns and more proficient in the pattern language.

I’d love to hear about your first pattern writing project. Whether you started with me here or you’ve been doing it for a long time, I know you have a first pattern story that would benefit us all.
