This was a test for Romi Hill.
I would definitely make this again.
It’s an interesting construction, and I had a lot of fun working through the different sections. I love the lace pattern and the sturdy fit, and how the edges fold in nicely.
I found the pattern clear and easy to follow.
All techniques are explained, and Romi has great instruction videos. I liked especially the Russian join video, to attach new yarn, and the modified 3-needle-BO video (I should have seen this video before doing the BO, but looked only at the pictures which didn’t make it clear to me, but the video did).
For adding length, rows could be added in C2, C3 and C4 (I added 3x2 rows in each of these, because of tighter row gauge, and am happy with the final result).

Romi allowed to share progress pictures of this test on Ravelry. Short notes under my pictures show which section I worked on.

Measurements before washing:

• Body length, measured from armhole down to bottom of body: 32 cm.
• Body width, measured und the armholes: 63 cm.

Measurements washed and dried:

• Body length, measured from armhole down to bottom of body: 34 cm.
• Body width, measured und the armholes: 64 cm.

Gauge:
Swatch gauge, washed (3.0 mm needles):
25 sts, 33-34 rows = 10 cm.
The swatch was not stretched, only pinned down. So the cardigan might be stretched a bit horizontally, and more in the length when blocking.
I tried this with the swatch and it should work. (The gauge was written as stretched in 1st test version, but got corrected to only wash and let dry - I hope my row gauge won’t come out too tight.)

Swatch gauge unwashed was about 26 sts, but luckily the sweater gauge is looser than this.

Sweater gauge unwashed (3.0 mm needles):
Measured in section 4, stockinette: 23.5 sts, 34 rows.

Sweater gauge washed, stockinette:
23 sts and 32 rows = 10 cm.

Needles:
Main needle: 3.0 mm (Addi lace)
DPN: 2.5 mm because I don’t own a 2.75 mm needle - tried not to work too tight.

Size:
Size 4. I’m between two sizes, so if the cardi gets a bit tighter, it should fit me even better.

Project notes:

• Section 7: It was helpful to place a marker on working needle to mark the additional repeats of rows 3-4 (placed after first 15 sts on working needle for size 4). Section 7 ends with 70 sts on working needle and 31 sts on DPN.
• Sleeve stitches bound off at end of section 11, to get the stitch holders out of the way.
• To lengthen the body, I worked 6 additional rows (3 × 2 rows) for C2, C3 and C4.
