The Romy short-sleeve top is the easiest and quickest shirt pattern; perfect for beginners who are learning to sew with knit fabrics. It can be sewn entirely with a serger and there is no hemming, only bands. In this post, we will show you how to transform it into a t-shirt.
A great upcycling project if you have worn your sweater plenty of times and now want to transform it and wearing in the summer.
Here is the original sweater, as it was made. Grab a ruler and tailor chalk, we’re about to start!
Starting 5 cm (2”) from the armhole corner, trace a line that ends up square with the fold line and cut.
Do it on ONE sleeve only. Trust us on this one, lol!
Here we are cutting the sleeve of a finished garment, but you can also do the same process on your pattern piece if you want to sew up a t-shirt in no time.
Take the first sleeve that you cut out and place it on the other sleeve. Using what you cut off ensures that both sides will be identical.
Voilà! You are ready to hem the sleeve openings! We will be using a Twin needle on our Janome MC 6700P for this, but it could also be done with a coverstitch machine, such as the Janome CoverPro 900CPX, Janome CoverPro 1000CPX, Janome CoverPro 2000CPX OR, the incredible BRAND NEW Janome CoverPro 3000 Professional!
We always recommend finishing the raw edge of any hem with the serger, making sure the tension is correct so that the fabric edge stays nice and flat, not stretched out. The overlock seam will add body and give a cleaner, more professional finish at the end. We’re using the Janome AT2000D Air Thread serger, but any Janome serger will do this step.
Install the Twin needle on your machine using 2 spools of thread on top; one for each needle, and one thread in the bobbin underneath. Many Janome machines come with a 2mm wide Twin Needle, but other sizes are available. Check with your Janome Dealer.
VERY IMPORTANT, use the STRAIGHT STITCH setting for topstitching!
Fold and pin the sleeve opening by 2 cm (3/4”) to wrong side.
Topstitch 2 cm (3/4”) from edge, making sure to catch the overlock seam in the topstitching. Do NOT stretch as you sew.
On thinner knits, some tunneling might occur where the fabric draws up between the needles, but the serger finish will help minimize it, as will adjusting the needle tension, if needed.
