Let's knit a sweater with
Phrancko's Seamless Set-in Sleeves


Create a custom-fit sweater pattern to your specific size measurements.

And make it the exact fit you want with the yarn and needles you choose.


Create a sweater pattern in multiple sizes which you specify exactly.

Then modify it with your unique design elements for publication wherever you like.


What kind of sweater?

We will create a pattern for a plain sweater worked from the top down.

The possible patterns are size inclusive. Patterns have been generated as large as 70 inch chest circumference.

It will have set-in sleeves architecture for the best underarm fit possible.

It is worked entirely in the round from the neck down.

And it’s totally seamless!

It does all this by using Phrancko’s Seamless Set-in Sleeve construction.

How difficult is the pattern?

Here's a SAMPLE PATTERN if you would like to check it out. (Note: It is not custom-fit for any particular baby or size.)

The Craft Yarn Council would characterize the pattern as either “Intermediate” or "Complex.”

If you can knit Stockinette Stitch, work basic increases and decreases, cast on and bind off, then you can knit this sweater!

If you can also work a provisional cast-on, you can avoid the underarm bind-off and picked up stitches, but that is completely optional.

Why is it a perfect fit?

You specify the measurements of the person who will wear it, not the dimensions of the sweater itself.

You choose the fit you would like on that person, whether tight, standard, or roomy...or even snug, form-fitting, or oversized, all based on the amount of ease you desire.

You create only one swatch using the yarn, needles, and pattern you wish to use to determine the gauge of your personalized pattern.

In short, the pattern is written to your specifications of size and possibly multiple fits for one person using your particular stitch and row gauge.

Make the pattern your own design for publication in multiple sizes.

For a published pattern, you decide how many sizes you want in your pattern. From 3 to 9 sizes are possible.

Then either specify the exact measurements of each size or simply accept the suggested measurements for standard men's, women's, or children's sizes.

Choose your yarn in the colorways, fiber, or yarn weight that you like. You can also work it in lace or any stitch pattern you choose as long as you swatch that for your gauge measurements.

Use the basic pattern as a starting point to create your own design featuring Phrancko's Seamless Set-In Sleeves construction.

Once the pattern is generated, copy it to a word processor and modify the text to incorporate your own design features, whether colorwork, cables, pockets, alternative necklines, or whatever you decide will make the pattern your own unique design.

Publish your completed pattern in a magazine, on Ravelry, or anywhere else you like, leaving just one single statement in the pattern to properly acknowledge the contribution of Phrancko.com.
