Mathematical (Curve) Stitching 2026 - Questions

 Some Excellent Questions

Some excellent questions have come up about stitching the 3D cube.  

What do the symbols in the corners of your templates actually mean and want you to do when stitching the parabola?

How can you adjust the number of holes in the templates that I've given you?

 

 

Those symbols tell you where the vertex of your parabola is going to be.  The curved part of the parabola is going to be in that corner (the one with the symbol) facing out. 

Beside the blue circle I put "behind" which means you will stitch that first to give the impression of it being "behind" the other colour in dimension as well as actually being behind in stitching.  The red triangle had "in front" beside it.  You will stitch those after you have finished all the other parabolas of the first colour.  This will give the impression of foreground, and the stitching will be on top of the first colour.  The following video gives a demo of the placement of those stitched parabolas.

Fixing Templates

When you are given a template that does not have matched holes — in this case the cube was not accurate — one way to correct it is to redraw the lines with marker and then remark the piercing holes using a ruler or other guide. (or even by eye as long as you have the same number of holes on each side).  Once you have a template that works, you can save it and reuse it. 

 

RemarkingHoles 

 

Another excellent question was asked.  How do you use the blocklayer.com  program to create multi-segment designs?

I mentioned that it was great for creating the circles with specific holes but I didn't go into details about line segments.  A lot of the patterns that I showed you from that point on, I'd seen on the internet as stitched patterns and used the circles and drawn lines or used the stitched pictures and counted holes and made patterns.  I didn't spend a lot of time explaining how I made those patterns from pictures or from those basic circles.

 

Here is a more complete explanation.

Once you have your outer circle, with the number of holes that you'd like to work with, you need to create the inner structure — the line segments — by dividing the circle into sections.  That is why I recommend using a circle with 72, or 36 holes around the exterior.  It is easily divided by 4, 6 or 8 segments.  Use more holes if you are working with a large piece but that number works for me at the small size I'm working with.

 

Here is a small demo of how I work with the circle from blocklayer to create my template and I've attached a basic template (with the words blocked out) for you to use.  I've sent them as Word diagrams so that you can resize the pictures.

Mathematical (Curve) Stitching 2026 - Lesson 2

Using Parabolas with Circles

Lesson 2 Presentation

Parabolas can be used with divided circles to create interesting designs as well.

These can later be combined with the use of chords to create more complex designs.

The full protractor template that was given with the first handout will be useful here.  So will the site where you can create your own circles.

These patterns can be used with the stitching pattern for parabolas to create interesting designs.  Experiment with using the curved areas as well.

 Try stitching parabolas in the following areas of the circle. 


 




 

 

 

 






  



 

 

 



 

 

 





























Make sure you have the same number of holes across the top of the segment (arc) as you do down the side (radius).




Polygons

Interesting designs can be created with other polygons.  Mary Everest Boole. Introduced her students to the equilateral triangle (all sides the same length and all angles the same  60 ̊), the pentagon, hexagon, octagon and more.

Just as with the circle, the polygons can be divided into sections and parabolas can be sewn in the outer angles, the inner angles and combinations of the two.    

A hexagon can become a cube with the addition of some interior lines and if the parabolas are stitched in two colours to help show dimension.

Try dividing the triangle from the angle vertices to the center point,  Divide the lines you’ve created into equal sections ( adding up to the same number as along the side of the triangle) and use those new lines to create parabola like stitching.

Note:  my diagrams may not always have the correct number of dots (I have trouble drawing diagonal dotted lines and getting the number of dots that I want in this drawing program – so it’s do as I say and not as I do in those cases – making templates by hand is much easier)
