11 Step-by-step Guides on How to Sew a Flat Bottom Bag

Step 1: Prepare the Fabric

Before you can begin sewing your flat-bottom bag, you’ll need to prepare the fabric. Start by cutting your chosen fabric piece into two rectangular pieces – one for the bag’s top and bottom, and one for its sides. The size of each rectangle will depend on the desired size of your finished bag.

Once you’ve cut the fabric, make sure to press each piece with an iron (or by steam) to get rid of any wrinkles. This will help your bag maintain its shape and look its best.

Step 2: Sew the Top and Bottom Together

Now that your fabric pieces are prepped, it’s time to begin sewing! Begin by taking the two pieces of fabric meant for the top and bottom of your bag, and lay them out on a flat surface. Line up all four corners so that they form a rectangle shape with straight edges.

Next, use pins to secure the two pieces together at each corner – this will make it easier to sew them together once you get started.

Once the two pieces are pinned, use your sewing machine to sew around all four edges. Make sure to backstitch at each corner and also at either end of your line of stitching. This will help ensure that your bag remains secure even after prolonged use.

Step 3: Sew the Sides Together

Now it’s time to sew the sides of your bag together. Take the two pieces of fabric meant for the sides and place them right sides together, aligning all four corners. Secure the edges with pins and then use your sewing machine to stitch along both sides – again, make sure to backstitch at each corner and either end of your line of stitching.

Once you’ve finished the sides, turn the pieces right-side out and press them with an iron to make sure the seams are nice and crisp.

Step 4: Attach the Handles

At this point, you’ll need to attach handles to your bag in order for it to be functional. To do this, take a piece of webbing or fabric (depending on your preference) and fold it in half lengthwise. Then, use pins to secure the folded edge of the webbing to one side of your bag’s top rectangle.

Once that’s done, stitch along all four edges with a zigzag stitch. This will help ensure that the handles are securely attached to your bag.

Step 5: Attach the Bottom

Now it’s time to attach the bottom of your bag. Take the side pieces and line them up with the top rectangle, making sure that all four corners are aligned. Secure with pins before stitching along all four edges using a zigzag stitch – this will help make sure that the bottom is securely attached to your bag.

Step 6: Sew the Seams

Now it’s time to sew the seams of your flat-bottom bag. Start by laying out the bottom rectangle and side pieces so that they form a rectangle shape with straight edges. Make sure to pin each corner together before stitching along all four edges with a zigzag stitch – again, don’t forget to backstitch at each corner and either end of your line of stitching.

Step 7: Sew the Lining

Now that the outer shell of your bag is complete, it’s time to add a lining for added protection. To do this, take two pieces of fabric (the same size as your bag) and lay them out on a flat surface. Pin the edges together at each corner, and then use your sewing machine to stitch along all four sides – make sure to backstitch at each corner and either end of your line of stitching.

Once you’ve done that, turn the pieces right-side out and press it with an iron to get rid of any wrinkles.

Step 8: Attach the Lining

Now it’s time to attach the lining to your bag. Start by taking the outer shell and laying it down on a flat surface right-side out, then take the lining and place it inside (right-sides together). Line up all four corners so that they form a rectangle shape with straight edges, and then pin the edges together – this will make it easier to sew the lining in place.

Once you’ve done that, use a zigzag stitch to sew around all four edges of your bag. Make sure to backstitch at each corner and either end of your line of stitching.

Step 9: Sew the Opening

Now that your lining is attached, you’ll need to sew a small opening at the top of the bag (this will be where you insert items). To do this, start by folding down the top edge of your bag about 1/2 inch. Then stitch along the fold with a straight stitch – make sure to backstitch at either end of your line of stitching.

But be sure not to stitch all the way around – leave a gap of about 4 inches in the middle of your line of stitching. This will leave you with an opening that can easily be opened and closed.

Step 10: Reinforce the Seams

Now it’s time to reinforce the seams to make sure that your bag is as sturdy as possible. Start by trimming any excess fabric and then using a zigzag stitch to sew around all four edges of the bag – this will help prevent fraying and ensure that the edges stay secure.

You can also choose to add a decorative stitch along the top edge of your bag if you like. However, this step is completely optional. It’s purely for aesthetics.

Step 11: Attach the Label

The last step is to attach a label to your bag. To do this, take a piece of fabric or ribbon and sew it on one side of the bag with a zigzag stitch – again, make sure to backstitch at either end of your line of stitching. Then, use a fabric marker to write the label on the other side of the bag. This is a great way to personalize your bag and make it unique.

And that’s it! You’ve now completed your very own flat-bottom bag. Congratulations! Show off your finished product with pride – you’ve earned it.
