There’s a mathematical theory which we can use as a rule.
It is a sequence where last two figures are added together to make the next.
Here is a link to an article about a new children’s book about Fibonacci which has some lovely illustrations.
So, if you start with zero, add 1 ….. the first border will be one unit wide …
most of us work in inches or know how big an inch is, so we will say 1 inch.
The next border will also be 1, because 0 + 1 = 1
Mmm! Not rocket science, but not exciting either.
Next 1 + 1 = 2
1 + 2 =3
Starting to look OK
2 + 3 = 5
I like that!
But, what if we mix them up a bit?
It might work if the reddish border was pieced or applique, or the fabrics swapped around perhaps.
But I like this last one.
The first two, I wouldn’t use regardless of the fabric choice, from then on, I think I would use them, but would switch fabrics around more than I have with the examples.
The same for switching the sizes, the fabric has to work for the border sequence to work.
has an explanation of the Fibonacci Sequence which is worth looking at,
along with a table for how to use the table when designing quilts.
Have I ever used this theory before?
Would I use it?
Yes, but not all the time.
The most interesting thing I discovered was that the numbers work best for me when I use them out of order!
Like all rules in quilting, it’s a place to start, but the fabric, if there are pieced or applique borders to be included, the finished size required, the amount of fabric available, ……….
The best answer I can give is lay the quilt top out, or put it up on a design wall, and lay out the fabrics, see what looks best!
