Sewing knit hems with a three-thread serger edge

Valentine's Day One Seam Wrap

Super quick and easy 3-thread edge serge finish

By: Christine Jonson

This technique works especially well for light to medium weight sweater knits where a traditional hem is not best. I love this Missoni-ish fabric that is in my current collection, and thought it would be the perfect Valentine's Day topper in the reds and pink colorway. This wrap (One Seam Wrap from #1117) has only one seam that needs to be stitched for the underarm/sleeve. Once that is sewn the rest of the work is the edge stitching or rolled hem.

Here's what you need:
3 cones of thread
1/8" bias fusible seam tape
Rolled hem foot and plate

The Outfit...

I paired the One Seam Wrap with my Ruched Skirt(free pattern in the tips & how-to) made with black rayon jersey and the Keyhole Top (sleeveless and without keyhole) made with a wonderful textured knit from my stash.

Since I want this for Valentine's Day I chose a variety of red and pink threads to choose from then made my decision.

I changed the plate and foot on my serger for a rolled hem and did a few test samples to achieve the perfect stitch.

This is my Brother serger which I bought in 1980! I love it and it has given me years of excellent performance.

I cut the 1/4" bias tape in half because I only need it to be as wide at the rolled edge and don't want it to show on the wrong side. You can use fusible interfacing cut on the bias for this step as well.

Carefully press the bias tape along the edge of the wrap on the wrong side.

Press this on all the way around.

Edge serge on the right side of the fabric without cutting any fabric off. I flip the knife up and out of the way to be sure.

I control how thick the thread is on the edge of the fabric by pulling it slightly with my left hand as I guide the fabric with both hands.
