Fifi's Mitten Chart Generator

This mitten chart generator takes any gauge, and any hand measurement to output a chart that

will be almost exactly the measurement you need. This generator creates a blank chart that you

will fill in with your own pattern. 

Experience Level 

This is not a pattern to be followed step by step and assumes that you know how to knit a mitten

and how to read a chart. 

Yarn 

Any, but anything thicker than worsted weight is not recommend.

Gauge 

Any, but a gauge swatch is required 

Pattern Making 

The gauge on the charts comes out proportional, this means that the pattern you draw on the

chart will come out the same shape in the final mitten. 

PDF Output 

This generator produces a 4 page document. 

  1. Right hand chart

  2. Left hand chart 

  3. Thumb and project notes 

  4. Combined left and right hand chart 

Requirements

  • Windows Computer or familiarity with running python scripts

  • Printer 


    On Windows: Click the .exe file open and the program will run.  


    On Windows/Mac/Linux: Install Python, PySide6 and ReportLab in the terminal, then run the python file. You should always run programs in a virtual environment.



Hand Measurements




Measurements 

Hand width - Purple

Hand height - Turquoise 

Thumb height - Yellow

Cuff height - Blue


Ease

Include any ease that you would like in these measurement. The pattern will come out almost exactly the measurements that you put in. Use a flexible measuring table to see how it will fit. Remember that colorwork is less stretchy than stockinette. Use an existing mitten that you like as a reference. 


Final circumference

Depending on whether you chose a 1 or 3 stitch band, and what your gauge it, this will impact the final circumference of the mitten. The total circumference is calculated and printed on the PDF, located on the thumb page. If you are using worsted yarn a 3 stitch band will have a a big impact on the final circumference. If you are using fingering weight yarn then there will be very little impact.  


Knitting the Mitten


Ribbing

Add ribbing as you’d like. You can make a mitten with no cuff and only ribbing but I suggest adding at least .5 cm of cuff. In the program a value of .25 cm is the lowest that you can go. 


Increasing and Decreasing 

Use right and left leaning increases and decrease as needed. For example, m1r, m1l, k2tog, and ssk.


Thumb

The thumb assumes that you will pick up 1 extra stitch on each side of the thumb. I like to pick up two on each side and then k2tog on the first round.




When run you will see:
