One of my lovely nieces is learning to sew with a sewing machine. To help, I thought I would do a series of beginning sewing project tutorials. Today’s tutorial turns an old t-shirt into a market bag. I’m keeping it simple today, but in the future I’ll do a post on how to make it with and enclosed bottom seam and how to box the bottom. It’s a great way to turn t-shirts that you no longer wear into something useful. If you don’t have a sewing machine, you could even sew it by hand.

Materials:

• T-shirt
  • T-shirts with a high cotton content and no side seams work the best.
• Thread in your choice of color.
• Fabric scissors
• Sewing machine set up with appropriate needle and bobbin threaded in your color choice.
  • Note: Ball point needles are generally the best for sewing with knits. This project does fine with an all-purpose needle, though, so use what you have.

Preparing the shirt:

Lay the shirt out flat and smooth out any wrinkles. Since this one is just to add to my Aldi bag stash, I didn’t worry too much about wrinkles.

Cut off the arms including the armhole seams.

Cut off the neck about 2-3 inches below the neckband. My shirt is pretty big, so I went three inches below the neckband. With smaller shirts you can do less.

Cut straight across the bottom of the shirt to remove the hem. The hemline is often uneven on t-shirts, so focus on keeping the shoulder seams lined up, the shirt smooth and cutting a straight line that removes all of the hem.

At this point, you should basically have turned the t-shirt into a tank top. Now, decide if you want your bag to look like plastic grocery sacks that have the handles at the top sides (so, your tank top with the bottom sewn closed), or if you want the handles at the top middle, like a purse or market tote.

For the grocery sack-style, turn your shirt inside out and lay it flat, just like a tank top again. For the purse/market tote, turn it inside out and match the shoulder seams and armholes together, then lay it flat. I’m making a market style tote, so you can see it in the photos.

Once everything is lined up, pin along the bottom to hold it in place.

Sewing the bag:

Many sewing machines have an assortment of stitches to use with knit fabric. They are useful for keeping the thread from breaking when the fabric stretches. On my machine, they are labeled “stretch” and shown in brown. Zig-zag stitches also work well on knits.

You could use a stretch or zig-zag stitch for the bottom of the bag. Since it really shouldn’t be stretching much, I usually stick with a regular straight stitch set to a long-ish length of 3.

Regardless of the type of stitch you choose, I recommend sewing across the bottom twice to make it nice and strong.

The seam allowance, or distance between the edge of the fabric and the stitches, doesn’t really matter that much as long as you keep it the same all the way across. For this bag, I used a 5/8 inch allowance, marked on the footplate of my machine. To keep a straight line, focus on keeping the fabric lined up with the guideline for the seam allowance rather than watching the needle.

At the start , sew about 2-3 stitches then backstitch to secure the stitching before continuing to sew to the end. At the end, backstitch another 2-3 stitches, then sew to the end and cut the threads. Repeat the seam as close to the original line of sewing as possible to make it nice and strong.

Turn the bag right side out. Since knit doesn’t unravel, you could stop there and be done. I like to sew around the arm and neck holes to reinforce the t-shirts original shoulder seams and give it a more finished look.

Finishing around the t-shirt arm and neck hole handles:

I usually use a serger for this, but it’s not necessary. On a sewing machine, I do like to use either a zig-zag or stretch stitch since there is going to be more stretch on the handles so a straight stitch might break.

This time, I’m using a zig-zag stitch, keeping the stitch length set at 3 and using about a 1/2 inch seam allowance. If your sewing machine has a free-arm, it can make it easier to sew around the armholes if you use it. Sew around each arm hole and the neck hole separately.

To start and finish the zig-zag, I backstitched like normal. It looks a little messy that way. You could leave extra thread at the beginning and end, pull the threads to the back side and tie knots to secure them if you want a cleaner look.

That’s it. You now have a purse or reusable bag from what used to be an old t-shirt. Don’t throw the t-shirt scraps away. I’ll post some creative uses for them soon! To learn how to make this bag a little more polished, read my t-shirt bag upgrades post.

If you read through the tutorial and like the concept but don’t want to diy, I still have a few left in my shop on clearance here.
