I like fleece throws--they are so warm and cozy. Stores often have fleece yardage on sale at 50% off. 1 & 1/2 yards of fleece is perfect for a lap throw. But until recently, I've never had any success at sewing them on my domestic machine. The seams rolled and buckled. The reason is that fleece is a really a stretchy knit fabric.

Sergers do work but it is possible to sew a great seam on a regular sewing machine too. Here's what I do.

Put a walking foot on the sewing machine. The walking foot creates a balanced feed on the top as well as the bottom of the fabric, avoiding stretching it.
Choose a stitch recommended in your machine's manual for stretch fabrics. I use the "jersey stitch" on my Bernina
Fold the raw edge over to the back side of the fleece, wrong sides are together. 1/2" fold puts the raw edge on the inner left edge of the walking foot and the folded edge on the outer right edge of the walking foot. I use the walking foot as a guide so I don't need to mark or pin the fleece
Sew the seam on one side of the throw. You can either sew the entire seam to the end of the fabric or stop 1/2 inch from the end, fold over the seam on the next side, turn with the needle down and continue sewing. I find I get a neater fold if I sew all the way to the edge and then fold over the next side.
Let the walking foot feed the fleece under the needle. Don't pull or push the fabric which will stretch the fleece
Sew at a steady rate to create an even design in the stitching

In middle row of photos above, the seam on thewrong side of the throw is on the left and the seam on the front side is on the right.

Using a walking foot and a stretch stitch is a fast, easy, no-fuss way to finish fleece for a throw!
