I read a lot of sewing blogs....and it's amazing seeing all the different outfits people make.
I saw two patterns that looked like they'd fit into my mostly casual wardrobe -- by a company I'd never heard of - Jalie. So I ordered two and made one of each as a trial to check the sizing and see if I could use the cover stitch on my (older model) serger.
First was a dolman sleeved knit top (Jalie 3352) -- using some fabric I had on hand. I cut what I thought would be a good size -- with sleeves -- and used a twin needles for hemming. It's cute -- and looks like the pictures. But it's really too big (especially in the shoulder/underarm area), too long (by 2-3 inches), and the doubleneedle just didn't provide sufficient stretch. It's wearable -- as an oversized top. But I'm going to try again with a sleeveless version and adjust the size/length.
Next up was a racerback tank (Jalie 3245) -- again using fabric I had on hand. I cut the same size as the dolman sleeved top -- and had to cut off one inch at each size at the underarm-- for a total of 4 inches (I have to admit that I just serged the excess off - blending into the original seam line a few inches down). This time I used my coverstitch and it worked out fairly well. I couldn't stitch over serged seams neatly -- but the stitching looked great on the flat hems, around the arms and neckline. And after reading a few tips online for starting and ending each seam -- the results really look professional.
I didn't use any binding, but simply stitched the hems down.
