What You Need to Know Before You Start
A minky blanket is two layers of fabric sewn together, usually with minky (a soft, plush fabric) on one side and cotton or another minky on the back. The seams are finished so the raw edges don't show, and the result is a blanket you can wash and use for years. The basic process takes a weekend if you have a sewing machine, and the hardest part is keeping the slippery minky fabric from shifting while you sew.
Minky blankets work well as gifts because they're practical and feel expensive to receive, even though the materials cost between $20 and $40. You don't need advanced sewing skills—straight seams and a basic understanding of how to thread a machine are enough. The main challenge is that minky stretches and slides, so you'll need to use techniques that keep it in place.
Key Takeaways
- Minky fabric requires a walking foot or ballpoint needles to prevent puckering and skipped stitches, because the fabric is stretchy and slippery.
- Cut your fabric pieces larger than your finished blanket size, sew three sides with a quarter-inch seam allowance, turn it right-side out through the opening, and then sew the fourth side closed by hand or machine.
- Pinning minky before sewing causes permanent holes, so use pattern weights, clips, or spray starch to hold the layers in place instead.
- Wash your finished blanket in cold water on a gentle cycle and dry it on low heat or air dry to keep the minky soft and prevent pilling.
Gather Your Materials and Tools
You'll need two pieces of fabric cut to the same size. Most minky blankets are 40 by 60 inches (a good size for a lap blanket or crib blanket), but you can make them larger or smaller. Buy minky and a coordinating fabric—cotton, flannel, or another minky—in the same yardage. For a 40-by-60-inch blanket, you need 1.5 to 2 yards of each fabric, depending on how wide the bolt is.
For tools, you need a sewing machine, thread that matches or blends with your fabrics, a rotary cutter and mat (or scissors), a ruler, and a walking foot or ballpoint needles. A walking foot is a presser foot attachment that feeds fabric evenly and costs $15 to $30; ballpoint needles are cheaper (a pack costs $5 to $8) but work only if your machine handles stretchy fabric well. You'll also need pattern weights or clips to hold fabric in place instead of pins—minky shows permanent holes from pinning.
Cut and Prepare Your Fabric
Wash and dry both fabrics before you cut, because minky shrinks slightly and you want to account for that before sewing. Lay the fabric flat on your cutting mat and use a rotary cutter and ruler to cut two identical rectangles. If you're making a 40-by-60-inch finished blanket, cut each piece 41 by 61 inches to account for the seam allowance (a quarter inch on all sides).
Place one piece right-side up on a clean, flat surface. Lay the second piece on top with the right side facing down, so the two right sides are touching. This is called "right sides together" and it's how you get a seam that looks neat on the outside of the blanket. Use pattern weights or large clips to hold the corners and edges in place—do not use pins on minky.
Sew Three Sides of the Blanket
Install your walking foot if you have one, or insert a ballpoint needle into your machine. Thread the machine with thread that matches one of your fabrics (or use neutral gray or tan thread that blends with both). Set the stitch length to 2.5 millimeters, which is slightly longer than a standard seam and helps prevent puckering in stretchy fabric.
Starting at one corner, sew along the first long side with a quarter-inch seam allowance. A quarter inch is the width of a presser foot, so align the edge of the fabric with the edge of the foot and sew straight. When you reach the corner, stop with the needle down, lift the presser foot, turn the fabric 90 degrees, lower the foot, and continue sewing the next side. Repeat for the third side.
Stop before you reach the end of the fourth side—leave a 6-to-8-inch opening unsewn. This opening is where you'll turn the blanket right-side out. Backstitch at the beginning and end of each seam to lock the thread.
Turn the Blanket Right-Side Out and Close the Opening
Trim the corners diagonally, cutting away the fabric at a 45-degree angle about a quarter inch from the seam. This reduces bulk so the corners lie flat when you turn the blanket. Be careful not to cut into the seam itself.
Reach into the 6-to-8-inch opening and grab the fabric on the opposite side. Pull gently and steadily until the entire blanket turns right-side out through the opening. The seams are now on the inside and the right sides of the fabric face outward. Use a point turner (a plastic tool that costs $3 to $5) or a chopstick to push the corners out so they're sharp and square.
Press the blanket with an iron on low heat, paying special attention to the edges and the opening. Fold the raw edges of the opening inward a quarter inch and press them flat. You can now close the opening by hand using a ladder stitch (also called a slip stitch), or you can sew it closed on the machine. For a machine-sewn closure, sew a quarter inch from the edge all the way around the blanket, which will close the opening and create a neat border.
Finish and Care for Your Blanket
Once the opening is closed, your blanket is complete. You can topstitch (sew a visible line of stitching) around the perimeter if you want a decorative finish, or leave it as is. Topstitching is optional but makes the blanket look more polished.
Wash the blanket in cold water on a gentle or delicate cycle with mild detergent. Do not use fabric softener, which can reduce the softness of minky over time. Dry on low heat or air dry by laying it flat or hanging it. High heat damages minky and causes pilling. The blanket will soften with each wash.
Troubleshooting Common Problems
If your seams pucker or the machine skips stitches, you're likely using a regular needle on stretchy fabric. Switch to a ballpoint needle or use a walking foot, which feeds the fabric evenly and prevents puckering. If the fabric shifted while you sewed, you didn't use enough pattern weights or clips—use more next time and space them closer together.
If the minky side feels rough or pills after washing, you may have used too high a heat setting or too vigorous a wash cycle. Wash on gentle and dry on low heat from now on. If the seams are visible from the outside, you may have sewn with too wide a seam allowance—aim for exactly a quarter inch next time.
Frequently Asked Questions
Can I use a regular needle instead of a ballpoint needle?
A regular needle can work if your machine handles stretchy fabric well, but ballpoint needles are designed to slide between fibers instead of piercing them, which prevents skipped stitches and puckering. If you're new to sewing minky, start with ballpoint needles—they cost very little and solve most problems.
What if I don't have a walking foot?
A walking foot is helpful but not required. Use ballpoint needles, reduce your stitch length slightly, and use pattern weights instead of pins to hold the fabric steady. Some sewers also use spray starch to stabilize minky before sewing, which reduces slipping.
How do I prevent the minky from showing permanent holes from pins?
Don't use pins at all on minky. Instead, use pattern weights (flat metal or plastic discs that hold fabric down), large binder clips, or quilting clips. You can also use temporary spray starch to hold the layers together while you sew.
Can I make a larger blanket using this method?
Yes. Cut your fabric pieces to your desired finished size plus one inch (half inch on each side for seam allowance). The process is the same—sew three sides, turn it right-side out, and close the opening. Larger blankets take longer to sew but follow the same steps.
What should I do if the opening doesn't close neatly?
If you're hand-sewing the opening with a ladder stitch, take small stitches (about a quarter inch apart) and pull the thread snug after every few stitches so the opening closes invisibly. If you're machine-sewing, use the same quarter-inch seam allowance you used for the other sides and sew slowly so the stitches are even.
