Pattern Inspiration

A long sleeved, lightweight sweater with eyelets down the sleeve has been on my “to-design” list for a while! So when I saw the call for the Crochet Foundry spring issue, I knew that was the design that I wanted to propose.

I have a thing for eyelets. They are such an easy way to add flare and class to a crochet garment. I just love how elegant they look! I also love picot trims! You’ll find this style of trim in a number of my designs. I used both eyelets and a picot trim to give this design the look I wanted and I couldn’t be happier with how it turned out!

Pattern Details

The Plumbago crochet sweater is a top down, raglan style workup. This pattern is rated intermediate, mostly because it is a garment that requires some shaping, increases and decreases, and sizing knowledge. The stitches, however, are very basic and beginner friendly.

Plumbago is worked from the top down with just a bit of seaming at the sleeve cuff. Everything else is worked in the round, joining at the end of each round and turning.

The Plumbago Sweater crochet pattern comes in 9 sizes ranging from women’s XS to 5X.

Yarn for the Eyelet Stitch Crochet Sweater

This crochet sweater is made with fingering (#1) weight yarn. I used WeCrochet Gloss fingering for my sweater.

Gloss Fingering yarn is a merino wool/silk blend. It is a dream to work with and comes in 17 beautiful colorways.

Pattern Notes:

Pattern is in US terms.

Pattern is worked in the round and joined to the first st in each round. Working the Lch and turning each round gives you a straight seam down the back of the garment.

Pattern is worked from the top down in a raglan style workup.

Ch-2 space is not counted in the final stitch count at the end of each round.

Ch 1 used to create the eyelets in the sleeve IS counted as a stitch.

Starting Lch does not count as the first stitch unless stated otherwise within the pattern.

Pattern is written in the smallest size with the additional sizes in parentheses as follows: XS (S, M, L, 1X)(2X, 3X, 4X, 5X). If there is only one number, it applies to all sizes.

Eyelets will be offset from each other down the sleeve. They will not line up evenly.

  1. Is there a way of getting the pattern without purchasing the crochet foundry magazine?

  2. Hi Michelle. I have purchased the plumbago sweater.
    Is there a way to make the neckline a bit bigger?

    1. Hi! Yes, if you go up a hook size or two to start it will make the neckline bigger without having to change the stitch counts.
