A few years ago, I designed the PETIT Knitted Diaper Cover with Suspenders for La Oveja Lola online store and now we can also enjoy it here!
The PETIT knitted diaper cover with suspenders is made up of two separate pieces that are worked flat, starting at the bottom of the front piece. Once the crotch area is formed, we will knit the decorative border with a Butterfly Stitch and we will finish knitting a waistband in ribbed stitch.
Later, we will form the back piece and join both pieces from the sides. To finish, we will knit the suspenders and sew the buttons in place.
Available Sizes
In today’s post, you will find the step-by-step tutorial in images to knit size 6-12 months of the Diaper Cover, but this PDF pattern is also available in sizes 0-3 months and 3-6 months in my online shop.
As usual, you will find the instructions to knit this baby Diaper Cover in size 6-12 months on the text and images, but if you prefer, the downloadable and printable PDF is an ideal complement to make your work easier.

Advantages of the pattern in PDF
You can download it and check it whenever you need it without depending on the mobile connection.
You can print it to have it always at your side while you are knitting and making notes, tracking rows, etc …
You will have all the detailed instructions, row by row and stitch by stitch, so you will know always where each increase goes, what are the rows of bobbles, etc, without having to calculate it.
You will have a graphic guide of the pattern. A diagram where you will see in a very visual way the shape of the garment, the disposition of the stitches, the rows, the details, the different stitches, etc.
You will contribute to the maintenance of this blog and so we can continue spending time together 🤗

How to knit the PETIT knitted diaper cover with suspenders– Size 6-12 months
1. Knit the front part of the Diaper Cover
Cast on 15 stitches, knit the first row, and purl the second row.

From row 3, we will begin increasing to shape the front part of the knitted diaper cover.
Rows 3 and 5: k1, M1L, k13, M1R, k1
Rows 4 and 6: Purl all
Row 7: inc 2 sts, knit all
Row 8: inc 2 sts, purl all
Rows 9, 11 y 13: inc 3 sts, knit all
Rows 10, 12 y 14: inc 3 sts, purl all
Rows 15 y 17: inc 4 sts, knit all
Rows 16 y 18: inc 4 sts, purl all

Knit 22 rows in stockinette stitch (St st) (knit odd rows and purl even rows)

How to knit Butterfly Stitch
From now on we will begin to work the Butterfly Stitch, which will embellish our knitted diaper cover with suspenders.
To work this stitch you must knit the following 5 odd rows as follows:
Knit 2, *bring the yarn forward, slip 5 sts purlwise, bring the yarn back, k1* repeat from *to* 8 more times until there are only 2 sts left, k2.

Purl even rows.

On row number 11, knit 4, * with the right needle lift the 5 bars and knit 1, k5 *, repeat from *to* 8 more times until there are only 4 sts left, k 4.

Knit the waistband of the knitted diaper cover with suspenders
We are going to make the waistband of our diaper cover using 1 × 1 ribbed stitch. To do this, work 3 rows in a 1×1 rib. In row number 4, we will open the buttonholes to be able to later secure the suspenders.
Buttonholes row. 16 sts 1×1 rib, yo, k2tog, 20 sts 1×1 rib, yo, k2tog, 17 sts 1×1 rib.
Work 5 more rows in 1 × 1 ribbing stitch and on the sixth row bind off all the stitches.

Front crotch section ribbing
Pick up 67 stitches from the bottom of the diaper cover (26 st from one leg, 15 st on the inseam, and 26 sts from the other leg) and work 2 rows in a 1×1 rib.
If you prefer to continue following the row by row instructions, remember that you have at your disposal a downloadable and printable PDF with the detailed pattern and charts so that you do not miss a single detail!

In row 3 we are going to open the buttonholes as follows: 26 sts 1×1 rib, yo, k2tog, 5 sts 1×1 rib, yo, k2tog, 5 sts 1×1 rib, yo, k2tog, 25 sts 1×1 rib
Work 3 more rows in 1 × 1 ribbing stitch and on the fourth row bind off all the stitches.

2. Work the back of the diaper cover
To form the back piece of the diaper cover, cast on 15 st. Knit one row and purl the next row.
From now on, work as follows until you get 41 stitches:
Odd rows: k1, M1L, knit until there is only 1 st left, M1R, k1
Even rows: Purl all
Once you get these 41 stitches, cast on 2 stitches at the edge in every row (both odd and even rows) and work in stockinette stitch until you get 57 stitches.
Work in Stockinette Stitch for 22 rows.

Work in Butterfly Stitch in the same way that you did with the front piece and make the waistband in a Ribbed Stitch. Remember that for the back piece, you should not open the buttonholes.
Back crotch section ribbing
Pick up 81 stitches from the bottom of the diaper cover (33 sts from one leg, 15 sts from the inseam, and 33 sts from the other leg) and work 6 rows in 1×1 rib. On row 7, bind off all the stitches.

4. Sew up side seams
Face the reverse of the two knitted pieces and sew up the seams. You can also make this union on the right side of the piece using a vertical invisible seam.

5. Knit the suspenders
On the back piece, pick up 12 stitches for the first strap starting from stitch 12 to 23 (both included) and work in 1×1 rib until you get 37 cm. approximately. Bind off all the stitches in 1×1 rib.
To get even edges, it is very important that you slip the first stitch without knitting. If the first stitch of the row is a purl stitch, slip it purlwise, and if it is a knit stitch, slip it knit-wise.

Pick up 12 stitches for the second strap starting from stitch 35 to 46 (both included) and knit the same as in the previous strap.

4. Final Touches
Weave in all the loose ends and sew the buttons to the end of the suspenders.







In all the previous photos, you can see the PETIT Diaper Cover knitted with Nausicaa Merino Bambú quality in the three available sizes.


In these last two pics, the same model has been knitted using DUO Sandnes Garn in color 6841 Agua Marina. As I mentioned at the beginning of the post, this is a fantastic alternative to get all the benefits of both cotton and wool in a single fiber.

Hey! I bought the pattern and was making it. But I’m just facing one problem – after increasing, my edges are super uneven and just don’t look great. But yours looks amaaazzing. Do you have any tips for me? 🙁
This is the cutest thing I’ve seen all day! I think one day I’ll be brave and try and make a pair.
