We've been sewing for a while now and have been learning little tricks that work better than others when sewing Velcro, so today we're sharing them with you in case you're still struggling with it :)
1. The ideal needle
Velcro is made of plastic, so it's hard and thick. It's better to use a thicker needle, size 90–100. Ideally, use a needle for sewing jeans, which has a sharper point.
If you use adhesive Velcro, the best option is a nonstick needle, since it has a non-slip coating with NIT that makes less residue stick to the needle.
2. If you don't want to use pins to hold it in place… glue.
If you're using Velcro without adhesive, it's better to use some kind of fabric glue to secure it and keep it from moving on the fabric. You have Guttenberg or Sewline's water-soluble glue. Always test it first on a scrap of fabric to make sure it doesn't damage it. Apply a little in the center and avoid the area where you'll sew, so it doesn't stick to the needle. Another option is to baste it.
3. We change the presser foot
We'll replace the universal presser foot with the zipper foot. You'll see that it lets you see better where you're sewing and stitch closer to the edge of the Velcro.
4. If we use adhesive Velcro, oil is your best friend.
Exactly—we love Velcro that already has adhesive on it, but it's a nuisance because the glue stays on the needle, forming little clumps, preventing it from sewing properly, and tangling the thread. Before sewing, take a piece of paper, moisten it with sewing-machine oil—not olive oil or sunflower oil—and use it to clean the machine needle. This will help keep the glue from sticking to the needle.
When you finish one side, stop, clean the needle again, and keep going.
5. Zigzag
To prevent skipped stitches or keep the Velcro from shifting with the fabric, you can use a zigzag instead of a straight stitch. With each stitch, alternate between one that lands inside the Velcro and the other on the fabric.
I hope these 4 little tricks work really well for you when sewing Velcro without any problems. If you have a trick that works well for you, I invite you to share it in the comments :)
Happy sewing!
