Tie four strands together on a foam core board and put pins into the top knot and at the bottom of the two middle strands to keep those in place.
Take the outer right strand (pink) and pass it to the left side over the other middle two strands. Take the outer left strand (yellow) and pass it underneath the pink strand, behind the middle strands, and over the pink strand on the other side.
Pull the two strands tight. Now you just reverse what you did in the first step! Take the outermost left strand (which is now the pink) and lay it across the middle two strands. Take the outermost right strand (which is now the yellow) and pass it underneath the pink, behind the two middle strands, and over the pink on the other side. Pull these two strands tight until they make a knot with the woven strands from the previous step. That’s the hardest part! The rest of the steps just repeat these basic motions.
Repeat steps 1-3 with four more strands to make another knot right next to your first knot. Bring the two rightmost strands of the first knot to make a new group with the leftmost two strands of the second knot.
Repeat your basic knot with the new group by taking the outer right strand (purple) and passing it to the left side over the middle two strands. Take the outer left strand (green) and pass it underneath the purple strand, behind the middle strands, and over the purple strand on the other side.
Pull the two strands tight. Now reverse the first step! Take the outermost left strand (which is now the purple) and lay it across the middle two strands. Take the outermost right strand (which is now the green) and pass it underneath the purple, behind the two middle strands, and over the purple on the other side. Pull these two strands tight.
Divide the middle group of strands by moving the two leftmost strands left and the two rightmost strands right. Repeat the basic knot with both the groups and continue this process until you have done as many rows as you would like.
When beginning to make the actual curtain, I made 14 groups of rope, each group with four strands that were all 100 inches long. I found it made a neater knot at the top of the curtain to cut two strands of rope that were twice the needed length (so 200 inches) and then I hung the strands over the rod at the middle point and tied a knot to create a four strand group.
You can see that it’s really the same principle of making the basic knots in the steps with the yarn, but just on a much bigger scale. I just made the basic knot near the top of all the 14 groups and then made another row of knots beneath and between those knots (like in the yarn instructions). Then I moved down another row and made knots underneath the original knots and just kept alternating the rows of knots until I had done as many rows as needed. Make sure to keep stepping back as you make your knots to ensure that you are tying your knots into even rows. I kept a ruler handy so I could measure the distance between each knot in a row and the wooden curtain rod to make sure they would turn out even. Once I did five rows of even knots, I let the rest of the strands hang down to complete the curtain.
Once you finish braiding the ropes hang your new curtain in your desired spot. To finish, wrap masking tape (or other white tape, I used “dorm tape”) around the ends right where the rope hits the floor (my curtain is 6 1/2 feet tall). Cut through the tape, leaving 2/3 to half of the tape intact on the rope. This will help the ends to keep from fraying overtime.
