Crochet Techniques #6: Post (Treble) Ribbing Join

Updated: Jul 12, 2020

I have been so busy with other crochet projects and deadlines I have struggled to find the time to get this together, but yay - finally, I can share my little trick for joining raised treble ribbing in the round! I use this technique in my Rhythm of Life Alpaca Sweater, and whenever I am working raised treble ribbing in the round for beanies and other clothes. It produces a ribbing ridge on both sides of the fabric so the join is (almost) invisible.

My Rhythm of Life Sweater will be published in under a week, and to make sure there is some extra information on the Post Treble Ribbing join technique, I have put together this tutorial. There will be plenty of other patterns this applies to - I seriously use this all the time!

Rhythm of Life will be available as both a short bodice version and a long bodice version.

Yarn: @Scheepjes Alpaca Rhythm

Sized to fit: Bust 81-86cm, 91.5-96.5cm, 101.5-106.5cm, 111.5-117cm, 122-127cm

Not long now....

I am experimenting with Scheepjes very new "Metropolis" yarn at the moment, making a little project using 2 strands of the yarn to see how it works up, (and how it handles being washed in my washing machine). I thought it would be a great way to show the Post Ribbing Join. This yarn is much lighter in colour than that of my Rhythm of Life Alpaca Sweater project, and has very good stitch definition, so the technique will be easier for you to see with this yarn.

Metropolis is slightly heathered sock yarn, 75% Merino extra fine and 25% nylon, and available in 80 colours! Yes, ...80!

Some knowledge of post stitches is assumed for this blog post, but to clarify, in UK terminology:

a FPtr (Front Post Treble) is sometimes also called a RtrF (Raised Treble Front):

"Insert hook from front to back to front to go around post of indicated st, work a tr."

a BPtr (Back Post Treble) is sometimes also called a RtrB (Raised Treble Back):

"Insert hook from back to front to back to go around post of indicated st, work a tr."

When I describe Post Treble Ribbing in my patterns, Round 1 is composed of regular treble sts which act as the first set of posts to work around for the subsequent rounds, and is joined in the usual way, (with a slip stitch).

Subsequent rounds are alternating FPtr, BPtr stitches to create the ridged ribbing texture, and are closed with what I call a "Post Tr Join". (Note: The stitch count must be an even number for the alternating ridge pattern and join to work, so if you are out by a stitch and have an odd number of stitches, you want to "fudge" that into an even number in the round that precedes Round 1 of Post Treble Ribbing. Then you are good to go.)

The "Post Tr Join" comes into play at end of Round 2:

"Work last Post Tr in ribbing patt of round to last 2 lps on hook, insert hook in beg tr of round, yoh, pull through tr and all lps on hook."

The last post to work around for end Round 2 is easy to see compared to the subsequent rounds, and is fairly self explanatory.

For the more difficult subsequent rounds, I have made a photo series helps show where to insert the hook to go around the last post:

The first photo shows that the series of Post Tr Joins over previous rounds has created a very slightly thicker ridge (indicated in white), and that the round shown has been worked to the last st. This round happened to start with a BPtr, so the Post Tr Join will begin as a FPtr:

Ch1 between rounds

My last photo shows working a ch1 before turning, and my instructions describe turning first, but it matters not. The ch1 does not count as a stitch - it functions to elevate the hook to the height of the next row, and provide a little distance from the top of the Post Tr Join, so the beginning Post Tr stitch of the next round will not distort the textured ridge effect.

I think I am in love with this new Scheepjes yarn! I wanted to know how hardwearing it was, given it's a sock yarn - and I have not been disappointed. I threw my completed mystery project into the washing machine hoping it would survive, (and at the same time prepared for it to be ruined). Happy days!!! It came out beautifully softened, squishy and "fooffed", while still maintaining very good stitch definition! This is perfect for garment design.

My experimentation project accidentally turned into a new pattern - so I can't show you anymore of it for now. Next week I will be finally self-publishing my Rhythm of Life Sweater pattern on my Ravelry store and running a little competition to celebrate - stay tuned!

So much to do - happy stitching!
