Perfect Granny Square Crochet Pattern

Learn how to create a seam free, single sided Crochet Granny square for perfect results every time.

The humble Granny Square is the crochet staple of Nanna's everywhere, which is how it came to be known as a 'Granny Square'. Originally it was just called a crochet square.

The Granny Square is often the very first thing we are taught when learning to crochet, so it would follow that it would be simple to have a perfect square every time and those new to crochet often get discouraged when this is not the case.

However, to get a perfect square actually requires a bit of experience, good fundamentals and advanced row starting techniques, otherwise you are left with seams, the reverse side of stitches showing every second row or even a slight spiral effect.

This granny square is made without turning your work and has a right and a wrong side.

National Garment Cutter: system of cutting and fitting

I had promised you all photos of the NGC rulers some time ago and I had every intention of bringing them to you long before now. It was my wish to do so in conjunction with sharing the 'General Instructions' for use of the instruments and some additional thoughts from my own experience in using the system.

I shall be brief for now and at the very least have photos for you. The 'General Instructions' may be had freely from the 1884 edition.

National Garment Cutter rules in a various sizes

For those who would wish to start making the patterns themselves directly from the books that are publicly available, work from the assumption that the base measurement is 20 inches and then size up from there as that is the rule which is closest to a 1:1 ratio with a normal rule.
