How to Make Curtains From Canvas or Dropcloth

canvas curtains made for industrial window treatmentsCustom window treatments are great, but who can afford them? For large span windows, especially those of modern architecture or of converted historic warehouse lofts, there is a DIY industrial solution that will add a chicness to the space and will fulfill the need for function as well as form. Hanging from galvanized steel pipes and KeeKlamp brackets, canvas curtains counter the hard lines with a little softness, help anchor the room, and invite comfort to the living space. They are heavy duty, will keep the harsh sunlight out without blocking out too much light, they will not fade, and they will hold up wash after wash. Hinged rings make installing and upkeep a snap. Canvas on the roll can found in discount fabric outlets and is very inexpensive. If there are no fabric outlets near you, no worries—go to the local hardware store and buy painter’s drop cloths. They come in various sizes, so just pick the size you need.


Step 1

 Open Gallerymaterials to make curtains for industrial window treatmentsDetermine how many panels and how many yards:  Don’t worry about accurate measurements this early in the process. If you are making these curtains out of stiff raw canvas, you’ll need to account for shrinkage (from prewash) and allow for hems. Measure generously. Since the curtain width will be the width of the fabric (usually 50-70 inches), figure out how many panels (width) you’ll need to provide the desired coverage. For the panel length, measure from where the curtain rod rests to where you want the finished curtain length to fall. Multiply that measurement times the number of panels you want to make. Add a yard per panel (shrinkage) to that total and you have the approximate total yardage you’ll need for the project. If you are using drop cloths, then buy the readymade cloths in the appropriate size.


Step 2

 Open Galleryprewash fabric for making  curtains Prewash/preshrink fabric:  Whether you are using canvas drop cloths or canvas off the roll, it is important to prewash/preshrink the fabric. This way, if you want to be able to launder the curtains in the future, the curtains will hold their shape as well as their length. Using your home washing machine (for up to ten yards), wash the canvas in hot water and detergent to remove the stiffening sizing chemicals from the canvas. Check to see after the first washing if it is soft enough. Sometimes it takes a couple of runs through the wash to achieve the right feel. Tumble dry on a high-heat setting. This will shrink and soften the canvas even more. If you have more than ten yards of fabric, you’ll want to go to a local laundry mat and use the big machines.

Step 3

 Open Gallerycutting canvas to make curtainsCut canvas into long runs:  Again, don’t worry about precise measurements just yet. You’ll see, cutting to size and hemming after you hang the curtains will be easier this way! Roll the canvas on a tube to help manage while cutting. To cut away the frayed end of the canvas and to make a straight cut, fold the fabric end back onto itself and line up the selvage ends. Cut on the fold. Roll out the fabric to a length that is at least a foot longer than what you need the finished curtain to be. Repeat the fold-and-cut trick on the mark and make your second cut. Pick up the panel and lay it aside. Roll another length, lay the first on top and cut the second panel. Repeat using the top panel as a pattern for the remaining cuts.

Step 4

 Open Galleryfolding selvage edge of canvas fabric to make curtains

Fold, iron, pin, and sew selvage:  If you are using drop cloths, the edges will already be hemmed. If the canvas (off the roll) selvage is tight and not wavy, you might want to skip this step. Use your own judgement but usually hemming the selvage gives a cleaner more professional looking edge. On the ironing board, fold fabric edge in a half inch and press. Continue folding and pressing down the fabric length. Fold over again, press, and pin. After pinning all panel edges, sew with a good durable matching thread with a medium stitch length. Remember, always start a line with a few stitches forward, reverse, and forward again to prevent stitches from coming apart.

Step 5

 Open Gallerypinning loops on canvas curtainsPin on twill tape header and loops: Repeat the fold-and-press step to the top of each panel, but this time, you’ll want to insert the twill tape underneath the fold. Pin the fold and twill tape in place. To figure out where the five loops go, first fold the top of the panel in half and mark the centerfold with a pin. Fold an end to the center pin and mark the center of that fold with a pin. Repeat on the other side of the center panel top. This will give you the ends and three marks, which makes five placements for the loops. Slip the precut loops between the fold and the twill tape and pin in place. On the ends, you’ll want to come in a little (with the loops) from the thick folded ends so not to be too thick for your machine.

Step 6

 Open Gallerysewing canvas loops onto canvas curtains

Sew on twill tape header and loops: When you go to sew, carefully hand crank the machine to stitch through the thick layers at the start of the stitch run. Continue to machine stitch as your machine will allow. You will probably have to hand crank the other end as well to finish.

Step 7

 Open Galleryhanging canvas curtains from metal ringsHang curtains with hinged rings:  Hanging the curtains is made easy with hinged rings. Simply open the rings, insert through the twill loops and close again around the rails.

Step 8

 Open Gallerymarking hem on canvas curtainsMark and cut panels in place:  Spread curtain out to full width on rail. Decide where you want the finished end to fall. To the floor? Puddled? Just below the windowsill? If you want your curtains to go to the floor or if you want them to puddle, line a straight edge along the floor, and pressing the panel into the recess, measure or mark to include the hem allowance. For the shorter length, mark one side. Take the curtain down for the shorter length and use the fold-and-cut trick for a straight cut. If you want either of the two longer lengths, mark and cut while curtain is hanging.

Step 9

Hem curtain:  Using the same methods as you used for hemming the selvages, fold, iron, pin, and hem the curtains. No need to take them down to do this. Having them hang will help support the weight while you run them through the sewing machine. No, this does not make you lazy, it makes you efficient!
