How to Sew a Lined Tote Bag
A lined tote bag packs boxed corners, strap placement and bag assembly into one small project that uses barely half a metre of fabric. The finished bag holds its shape, carries a week of groceries and looks far better than most shop-bought versions.
Materials
- 0.5 m of sturdy canvas or cotton drill for the outer bag
- 0.5 m of quilting cotton or poplin for the lining
- Matching all-purpose polyester thread
- 1 m of 2.5 cm wide cotton webbing (a quick alternative to self-made straps)
Tools
- Sewing machine with a universal or denim needle
- Rotary cutter, ruler and cutting mat
- Pins or sewing clips
- Iron
Steps
- 01
Cut the pieces
Cut two outer panels and two lining panels measuring 40 by 45 cm, plus two strap strips 8 by 60 cm from the outer fabric. Keep a 1 cm seam allowance on every edge and mark the wrong side of each piece with chalk.
- 02
Make the straps
Fold each strap strip in half lengthwise with right sides together, press a crease, then open it and fold both raw edges in to the centre line. Fold again and topstitch down both long edges so the strap cannot twist or curl.
- 03
Attach the straps
On the right side of each outer panel mark points 8 cm in from the side seam and 3 cm down from the top edge. Baste the strap ends in place, checking that both panels are mirror images so the straps meet when the bag is assembled.

Sew the bag body
Pin the outer panels right sides together and stitch both side seams and the bottom. Repeat for the lining, but leave a 10 cm opening in the lining bottom for turning. Press all seams open and trim the bulky corners.
- 05
Box the corners
Match each bottom corner to its side seam, flatten it into a triangle and draw a 5 cm square across the point. Stitch along the line, then cut away the triangle outside it; this gives the bag its flat base and helps it stand up.
- 06
Join and topstitch
Turn the outer bag right side out and slip it inside the lining so the right sides face. Sew around the top edge, pull the bag through the lining opening, then press the top edge and topstitch 0.5 cm from the rim before closing the gap.
Fabric and interfacing for a bag that stands
A tote keeps its shape because of the body of the fabric and whatever is fused behind it. Cotton drill, canvas and mid-weight linen all work as the outer, while quilting cotton is a good lining but too soft to hold a bag on its own.
Interfacing changes the result more than the outer fabric does. Mid-weight fusible keeps the bag crisp and light, a thin foam layer gives a padded feel, and a woven canvas interlining adds structure that survives repeated washing.
Straps and how to reinforce them
You can make straps from the outer fabric, use cotton webbing, or fit leather handles. Self-made straps give the most control over width and colour, webbing is the fastest and strongest for the money, and both are sewn on the same way.
Reinforce every strap join with a square plus an X through the middle, or with two rows of stitching. The join carries the whole load of the bag and it is the first thing to fail when it is held by a single line of stitching.
Sizing the bag and scaling the pattern
The panel size sets the capacity and the corner square sets the depth of the base. A panel of 40 by 45 cm with 5 cm corners makes a grocery-sized tote, while 30 by 35 cm with 4 cm corners makes a small handbag.
Scale the panels, the corner square and the strap length together. If you widen the base without adjusting the straps, the bag hangs lower than the proportions suggest and the straps look short.
Boxed corners and the depth they create
Matching each bottom corner to its side seam turns two flat seams into a triangle. Stitching across that triangle at a set distance from the point converts that distance into the depth of the base.
Trim the triangles to about 1 cm and finish the raw edges if the fabric frays. On heavy fabric, trim the layers in steps so the corner presses flat instead of bulging at the base.
Extras worth adding, and washing
An inner pocket, a key clip, a magnetic snap or a stiffened base panel all turn a plain tote into something used daily. A separate base panel keeps the bottom from sagging under weight.
Pre-wash every fabric that goes into the bag, because mixed shrinkage can distort the finished shape. If the bag contains fusible interfacing, wash it cool and air dry it, since heat can lift the adhesive.
Frequently asked questions
- How much fabric does a lined tote need?
- About half a metre of outer fabric and half a metre of lining covers two panels plus the straps with a little spare. Buy more if the print runs in one direction and you need the pieces to line up.
- How do I make the straps strong enough to carry weight?
- Sew each strap join as a square with an X through it, or use two parallel rows of stitching. Attach the straps so the load runs down into the bag body rather than pulling only on the top edge.
- What needle should I use for a canvas tote?
- A 90/14 or 100/16 needle with a slightly longer stitch of about 3 mm. Over the thick strap joins, slow the machine down or turn the handwheel by hand so it does not skip.
- Can I make a tote without a lining?
- Yes. Turn the top edge under twice and topstitch, or bind the raw edges with bias tape. A lined bag hides the seams and looks neater inside, but the unlined version is quicker and lighter.
