DIY Vinyl Project Bag | Madam Sew

Free Project Bag Pattern with a Vinyl Window

A project bag for knitting, sewing or quilting can store and keep together the supplies for one craft project – elastics, fabric pieces, thread, buttons,... That is what this tutorials is about. I'm making a bag with a vinyl window, so you can see clearly what’s in the bag. Things don’t fall out, you can take it to a class and it is nice to look at if you use your favorite fabrics. This is not a new, original idea. You can find lots of tutorials online. But this is my version. I made this free sewing pattern as simple as possible. It is a beginner-friendly project. Of course, if you plan to make these project bags to sell or to give as a gift, you will probably want to add some extra topstitching and hide the raw edges better by adding some bias tape or binding on the inside.

If you have a project bag for every ongoing project, your sewing room will defintely feel better organized. I don't want to tell you how many unfinished project I have. More than two, that's for sure! Let's get started and make a whole bunch. If you don't feel like making project bags for all your craft projects yourself, we have some neat project bags in our store as well. They are one of our bestselling products!

I often have different sewing projects going on at the same time. Well, maybe ‘going on’ is not the right word for it. Some projects can lie around for several weeks or months. I’m easily sparked with enthusiasm to start something new. Lots of ideas but... too little time. I start drawing a pattern after dinner, cut the fabrics and then…Oops, I don’t have all the supplies. I’m missing some interfacing, a little trim or matching fabric... And what happens? The unfinished project lingers in my sewing room, somewhere, and I get a new idea a couple of days later, forget to go to the store, and I start a new project. Depending on my time and enthusiasm, the first project stays unfinished for... a while (or longer) and takes up space on my cutting table. Sounds familiar?

What You Need to Make a Project Bag

This project bag has a zipper, a window, and a little handle. It is about 14 inches by 15 inches in size.

      • Fabric for the outside 21 inch x 20 inch
      • Fabric for the lining 17 inch x 15 inch
      • Transparent vinyl for the window 11 inch x 11 inch, I used 100% polyurethane
      • A zipper, minimum 13 inch long. I’m using an 18 inch zipper. I just cut it down to fit the bag.
      • Medium weight to heavy weight fusible interfacing to give the backside some stiffness: 15 inch x 15 inch
Materials you need

Cut the Different Fabric Pieces for the Project

  • Lining fabric: 1 piece 15 by 15 inch + 1 small piece of 8 by 2 inch for the handle
  • Outside fabric : 1 piece 15 by 15 inch + 3 strips: 15 by 2 inch + 2 strips 11 by 2 inch
  • The interfacing: 1 piece 15 by 15 inchCut the transparent vinyl: 1 piece 11 by 11 inch.
Cut your fabrics into pieces

Also, cut a couple of 1-inch wide tissue paper strips. I use those to sew over the vinyl easily later on.

Reinforce the Lining

Apply interfacing onto the lining fabric. I use a mid-weight fusible interfacing. If you want, you can also add batting and quilt the big outside fabric piece and lining to one another.

Assemble the Handle of the Project Bag

Make the handle. Sew the long sides together, right sides facing each other. Turn right-side out and iron flat. Sew the 2 ends onto the lining, right in the middle of one edge. Look at the picture below to see how you can do this.

Install the Zipper

      • Take 2 fabric strips
      • Pin or clip the edge of 1 strip to the zipper coil, right sides facing
      • Sew it down with a zipper foot
      • Finish the raw edge with pinking shears
      • Now topstitch on the zipper. I use a regular foot for this step.

Repeat the previous steps for the other edge of the zipper with the 2nd fabric strip

Trim the zipper and lock the end of the zipper by sewing over it a couple of times.

Install the Window of the Project Bag

Put the vinyl flat on your table. You will need pattern weights as it will roll up. Clip an 11 inch strip right sides facing on the vinyl. Don’t use pins or you’ll make holes in the vinyl. Put the tissue paper strips between the vinyl and your presser foot. I just clip them onto the vinyl. You can rip them away afterwards. Attach the strip, stitching at ⅜ inch seam allowance.

Do the same thing on the opposite side of the vinyl with the other 11 inch strip. Press carefully on the cotton. Press both seams flat carefully. Make sure you do not iron directly on the vinyl. You can also add a topstitching if you want.

Assemble the Project Bag

Now grab the part with the zipper. Attach it to the top side with clips, sew, press open. Grab the last 15 inch strip. Attach it to the bottom side of the vinyl. First clip, right sides facing, sew at ⅜ inch, fold open, press on the cotton and add a topstitching, if you want. To have neat edges on the inside, I trim them with my pinking shears.

Before you move on to the next step, I trim all parts to the size of the 15 x 15 square and I must admit that because my sewing is not very accurate, I also had to trim a part of the square, the width now being 14 inch. You should cut the side strips at 2.5 inch or 3 inch instead of 2, if you want a perfect square bag in the end. When you cut down the zipper, make sure to hold the 2 parts together with a clip or a quick stitching.

make sure to hold the 2 parts together

Open the zipper at least 3 inch. Place the part with the window right sides facing with the outside fabric. Pin or clip them together. Sew all around at ⅜ inch.

Now we will attach the lining fabric. Place it with the right side on the wrong side of the window. Pin or clip together, sew all around on the stitching that is already there, but this time you need to leave an opening at the bottom edge. Make it at least 3 inches wide. This is a turning hole, and you’ll need some space for the zipper and the vinyl to go through.

Trim the edges a little.

Turn the bag right side out through the turning hole. Now you can close this opening with a hand stitch. When that is done, you have to turn your fabric right sides out through the open zipper.

Adding the lining separately from the outside fabric and 2-step-turning makes the raw edges disappear between the lining and the main fabric. If you attach the 2 fabric layers in 1 step, you will see the raw edges on the inside of your bag. It’s up to you!!

I already made two project bags this week! With this pattern, you can make them in any color or size you like, maybe change the size of the window or make the handle longer. They are easily washable and customizable. I'm very curious to see what your version looks like!

finish project bag

Because of the success of this project bag tutorial, we decided to add a project bag to the Madam Sew store for the people who don't feel like making bags themselves or need some bags urgently. We developed this bag with all of you in mind. A studry bag, see through, lot's of space for all your sewing tools and notions. Check out how lovely the Madam Sew project bags turned out!

I love this idea, I don’t sew much anymore but do a lot of knitting and crocheting and do have a lot of projects going during the year. This will be a great idea to keep my project yarns with patterns together. Thank you for sharing.

Rachel

Thank you for the instructions and hints that you gave for the project great idea

An, I am so in love with this project. I was about to push another project into a plastic bag when I found it. I’ll shoot you pix when I’ve got one to show.

Thanks for the easy steps. One of my diagnoses is ADHD and I can do anything if its is broken into steps.

You can chop off this part of the comment and that’s okay with me but I want to you to know me, too: https://onestitchsavesnine.com.
