Minky Tip #1:
Don’t allow the fabric to stretch as you cut it. This is especially important if you’ll be sewing it to another non-minky piece of fabric, which most likely won’t have any stretch. Let the fabric lay flat, and adding a few pins here and there to keep the selvages together (if you’re cutting with a folded edge) can help to reduce it slipping out of place while cutting.
Minky Tip #2:
Pin, Pin, Pin!!! Was that clear? Whether you’re sewing minky to minky, or minky to another fabric, pinning every 1″ along the edges of the fabric will make a huge difference as you sew. Not enough pins means that the fabric will likely slide under the presser foot, and stretch as the feed dogs try to guide it, which can result in puckers. I’m not exaggerating when I recommend to pin it every 1″. Even a 2″ gap between pins can allow the minky to slip and stretch. It’ll be more than worth the extra time it takes to pin every 1″. If you’re really dreading the pinning and are looking to save a bit of time, you can also use Wonderclips (affiliate link), as they’re a bit quicker to pop on and off as you sew.
Minky Tip #3:
Use a walking foot (affiliate link), also called an Even Feed Foot. I know a lot of people who don’t think a walking foot is necessary and get by without one, but they are so worth the $20-$30 investment. I purchased a generic brand on Amazon for under $20, and it works wonders. The brand I use is Distinctive, and will fit most sewing machines. A walking foot has feed dogs on the presser foot, allowing both the top and bottom layers of fabric to be grabbed and pulled along at the same rate. Normally fabric is guided by the bottom feed dogs on your machine only. Having the fabric fed evenly under the presser foot is another huge help in preventing the fabric from slipping and stretching while being sewn.
Minky Tip #4:
Prewash any fabrics being sewn with the minky. Minky will not shrink, so does not need to be prewashed, but always prewash all other fabrics being used in the project to prevent any shrinking problems with your finished project.
