A crib skirt is a fabric panel that hangs from the crib rail to the floor

A crib skirt (also called a dust ruffle) is a single piece of fabric or a pleated panel that attaches to the crib rail and drapes down the sides and foot of the crib to hide the underside. You make it by measuring your crib, cutting fabric to size, adding a casing at the top to slide onto the rail, and finishing the bottom edge. The whole project takes four to six hours for a beginner and requires only a sewing machine, thread, scissors, and a measuring tape.

The skirt sits between the mattress and the crib rail, so it does not touch the baby. You can make it from quilting cotton, linen, or any medium-weight fabric that washes well. Most crib skirts are a single layer with a finished hem, though some sewers add a ruffle or pleats for decoration.

Key Takeaways

  • Measure your crib's rail height and the distance from rail to floor on all four sides, because cribs vary in depth and width.
  • Cut one piece of fabric for each side of the crib (three or four pieces depending on whether you cover the foot end), adding half an inch on all sides for seams.
  • Fold and sew a casing (a tube of fabric) at the top of each piece so the crib rail can slide through it.
  • Hem the bottom and side edges with a straight stitch or a narrow rolled hem, then slide the casing onto the rail.

Measure your crib before you buy fabric

Take three measurements: the height from the top of the rail to the floor, the width of each side of the crib, and the width of the foot end (if you plan to cover it). Write these down. Standard full-size cribs are roughly 28 inches wide and 52 inches long, but portable and mini cribs are smaller, and some vintage cribs are larger.

Measure from the outer edge of the rail down to the floor on at least two sides, because the floor may not be level. If the measurements differ by more than a quarter inch, use the longer measurement so the skirt reaches the floor on all sides. Add one inch to the height for the casing and seam allowance.

Sketch your crib from above and label each side with its width. This prevents mistakes when you cut. Most sewers make four pieces: two long sides, one short foot end, and one short head end (though the head end is often hidden by the headboard, so some skip it).

Cut and prepare your fabric pieces

Lay your fabric on a flat surface and use a measuring tape and chalk or a fabric pencil to mark the cutting lines. For each piece, add half an inch on all four sides beyond your measurements — this is your seam allowance. So if a side panel is 20 inches wide and 18 inches tall, cut it 21 inches wide and 19 inches tall.

Cut slowly with sharp fabric scissors or a rotary cutter. Uneven cuts make seams harder to sew straight. If your fabric has a pattern or nap (like corduroy), lay all pieces in the same direction so the pattern runs the same way on every side.

Before you sew, press each piece with an iron on medium heat to remove wrinkles. Wrinkled fabric is harder to measure and sew accurately.

Sew the casing at the top of each piece

The casing is a folded tube at the top of the skirt that the crib rail slides through. Fold the top edge of one piece down one inch toward the wrong side (the back of the fabric), then fold it down another inch. Press with an iron. This creates a half-inch tube when you sew it.

Pin the fold in place. Sew along the bottom edge of the fold with a straight stitch, using a thread color that matches your fabric. Sew slowly and keep the line straight — this seam holds the skirt on the rail. Backstitch at the start and end to lock the thread.

Repeat this step for every piece. If you are making four pieces, you will have four casings, one on each panel.

Hem the bottom and side edges

Fold the bottom edge of one piece up half an inch toward the wrong side, press it, and pin it. Sew with a straight stitch close to the fold. This is called a half-inch hem. Fold it up another half inch, press, pin, and sew again. You now have a finished hem that will not fray.

Alternatively, use a narrow rolled hem if your machine has that setting — it uses less fabric and looks neater on lightweight materials. Check your machine manual for the rolled hem foot and settings.

For the side edges, fold each side in half an inch, press, pin, and sew the same way. Do this on both sides of each piece. The head and foot ends of the skirt will have two hemmed sides each; the long side panels will have one hemmed side (the outer edge) and one side that will sit against the crib rail.

Attach the pieces to the crib rail

Slide the casing of the first piece onto the crib rail. Start at one corner and work slowly so the fabric gathers evenly. The casing should slide smoothly — if it is too tight, the fold may be too narrow, and you will need to remove it and re-sew with a wider fold.

Once the first piece is on, slide the second piece onto the same rail, overlapping the corner by about an inch. The overlap hides the gap between pieces and looks finished. Repeat for the third and fourth pieces.

Step back and check that the skirt hangs evenly and reaches the floor on all sides. If one side is shorter, you may have measured unevenly or the floor is not level. You can remove that piece, add a strip of fabric to the bottom, and re-hem it.

Troubleshoot common sewing problems

If the casing is too loose and the skirt slides off the rail, the fold is too wide. Remove the piece, cut away the casing, and re-fold it with a narrower width — try three-quarters of an inch instead of one inch. Sew it again and test it on the rail before moving to the next piece.

If the hem puckers or looks wavy, you may have pulled the fabric too tight while sewing. Use a lighter touch on the presser foot and let the machine feed the fabric at its own speed. If the thread breaks, check that the bobbin is wound evenly and that the needle is inserted correctly (consult your machine manual for the exact steps).

If the pieces do not meet at the corners, you may have cut them too narrow. Measure the gap and add that width to the next piece you cut. Keep notes so you remember the exact measurements for future repairs or replacements.

Frequently Asked Questions

Can I use a crib skirt with a mesh crib liner?

Yes. The skirt hangs on the outside of the rail, and the mesh liner sits on the inside, so they do not interfere. The skirt hides the underside of the crib while the liner protects the baby from bumping the rails.

What fabric works best for a crib skirt?

Quilting cotton and linen are durable and wash well at warm temperatures. Avoid stretchy fabrics like jersey or knits, which distort when you sew them. Avoid heavy fabrics like denim, which are hard to fold and sew a casing into.

How do I wash a crib skirt?

Remove it from the rail, machine wash in warm water on a gentle cycle, and tumble dry on low heat. If the casing loosens after washing, you can re-sew it or slide it back into place by hand. Wash it every two to four weeks or when it gets visibly soiled.

Do I have to cover all four sides of the crib?

No. Many parents cover only the two long sides and the foot end, leaving the head end bare because a headboard or wall hides it. Measure what is visible from the room and cover only those sides if you prefer.

Can I add a ruffle or pleats to the skirt?

Yes, but it requires extra fabric and more sewing. Cut strips of fabric twice as long as the bottom edge, gather them with a running stitch, and sew them to the bottom edge before you hem. This adds two to three hours to the project and uses 50 percent more fabric.
