Although they look complicated, mini blinds are simple to customise, including shortening or adjusting the length of the cord. Shortening a long cord can help your mini blinds look more attractive. It can also make the mini blinds a bit safer for children and pets, if you can cut the cords short enough to keep them out of reach. Don't rely only on shortening cords to keep children safe, however. The adjustment should be used in conjunction with other safety mechanisms.
Drop the blinds to their lowest possible position. This helps to ensure that you don't cut the cord too short, which can prevent the blinds from lowering completely.
Push the tassel, or the small knob at the end of the cord, up out of the way to reveal the knot.
Place a paper clip or clothespin on the cord just below the tassel so it doesn't fall off the cord while you're working. This will save time later, since you won't have to thread the cord through the tassel.
Cut the cord to the desired length.
Tie a knot near the end of the cord, about 1/2 inch from the bottom.
Remove the paper clip or clothespin and gently slide the tassel down to the knot.
Pull the tassel slightly to determine whether it will slip over the knot. Don't pull it completely over the knot, just find out whether a single knot feels secure or a double knot is needed.
Push the tassel back up and tie a second knot directly over the first knot, enlarging it, if needed.
Cover the knot with the tassel by pulling it back down.
Cut off any remaining cord sticking out from the bottom of the tassel.
Make the cords on blinds next to each other a uniform length by lowering the blinds, then measuring from the top of the cord and marking a spot to trim each cord.
Don't tie a double knot without first checking the fit of the tassel. A double knot may be too big for some tassels to cover.
