These are both extremely simple, but they have a nice cottagecore aesthetic if you work them up in rustic cotton (or weaving threads held together).
The towel pattern includes a quick (2018-ish vintage?) tutorial .PDF to help you make a button to hold it in place. You may not even need the tutorial—it’s basically two large buttons sewn together with some wrapping around the shank—but just in case, it’s there.
This entry is photo-heavy! Essentially, the steps are simple: with the WS facing you (and the tail from the cast-on edge on the lower righthand corner), pick up 31 sts from the RS along the selvedge sts. Once that’s done, flip the work again so it’s RS up, and add 30 sts using the cable cast-on, for a total of 61 sts. Work continues from there with a repeat of the mitered square instructions from Day 1. But this may not be intuitive at first, so we’re going the photo tutorial route.
Work Continues: Attached Mitered Squares (Make 13).
The previous step ended with a bound-off mitered square. One st is live on the needle, with the working yarn attached. The RS (right side) should look similar to the sample in the photo below.
Now turn the work so that the WS is facing up. Leave the live st on the needle, and continue not breaking the working yarn. (Note the angle of the decrease spine. For the first square, the cast-on tail will also be in the lower right corner; for the rest of the attached squares, the scarf will trail out from the lower edge, so it will be a little more obvious how to orient each new square.)
Using the working yarn, pick up 30 sts at the rate of 1 st per selvedge. Sts are picked up from the RS, with the WS facing you. With the loop left on the needle from the bind-off, you’ll have 31 sts total.
For the sample shown, I picked up sts from only the back leg of each selvedge st, to create a pronounced faux seam. You can pick sts up from both loops/legs or just one.
After picking up sts until you have 31 sts, turn work RS up again. It should look similar to the photo below.
Starting between the last two sts, CO 30 sts using the cable cast-on method, for a new total of 61 sts.
(I am working a few days ahead, so there’s more scarf in the photo than there should be at this point, but other than that, work should look similar to the photo below.)
Once all 61 sts are established, repeat Rows 1-5 from Day 1. (They’re reproduced below, so you don’t have to click back.)
Row 1 (RS). sl1, k remaining. Row 2. sl1, k29, p1, k to end of row. Placing a removable stitch marker on the purled middle stitch is optional. The purled stitch is referred to later as the middle stitch. Row 3. sl1, k to 1 before middle st, s2kpo, k to end of row (2 sts dec) 59 sts remain. Row 4. sl1, k to middle st, p middle st, k to end of row.
Repeat Rows 3 & 4 until 5 sts remain, ending with a Row 4 repeat.
Row 5 (Bind Off). sl1, s2kpo, slip previous st over, k1, slip previous st over. Do not break yarn. Leave last st on needle.
For squares 2-14, go back to the beginning and repeat this section.
