softbox size

So I had a thought. For light modifiers I have a rather large softbox (used for the main light) an umbrella (for fill) and a piece of tinfoil (to make a smaller opening the light for a hairlight).
I really want to be able to create a more moody lighting setup. I usually turn my fill down and back my main way up (so that it's smaller). It works okay. However I was thinking I needed a smaller softbox, but I really can't spring for one right now. Do you think taking a black piece of fabric and draping it over half of my softbox to give it a smaller opening would be the same? If it works it's certainly cheaper and would be faster than changing out the softbox.

Have you thought about putting a grid on the soft box? I know some of them are able to use one. Some of profoto's boxes have black strips that velcro on so you can narrow the beam, I'm sure it wouldn't be too hard to DIY some.

Take a piece of fabric a little bigger than your softbox.  Cut an opening in whatever size you want to change the box to.  You can make round, square or rectangular openings.  Make more than one.  You then attach these to your softbox with velcro.  You can add louvers or grids as well to make the light more directional.

Oh Ed that was a good idea. I was going to drape a black piece of cloth over the top, but then I have a horizontal light, not really what I wanted. Cutting a hole in fabric is brilliant! Who needs lots of expensive stuff?

I don't really understand grids. I guess I should look it up.

My favorite softbox for boudoir is my 1 x 6 profoto.  It's narrow width allows for more shadows & fall off.  I love it!

You could definetely modify a current softbox by doing what's been suggested in previous posts by covering up part of the light.  I also want to get a grid for it but they are like $500 ouch!

I like my 1x4 Creative Light strip. Less than $100 for a grid too.

Hm, I am going to have to modify my softbox to be a strip. I tried Ed's suggestion at my last shoot and cut a hole in some thick black fabric, but I just did a smaller rectangle. It worked well, but I will be trying the strip thing at a session I have in 2 and a half hours.

I measured my softbox, took those measurements to my seamstress and she took three pieces of cloth to make a new smaller sized opening for my softbox.  Fisrt she took a piece of thin silver material and sewed in velcro the same size as the original white cover, then she took a piece of thin black material and stitched it over the front of the silver, then she cut the new sized hole through both pieces and sewed a small rectangular piece of white rip stop nylon across the hole. The silver reflects the light back inside the box so all of it will exit through the hole, the balck makes sure none of the extraneous light will be bright enough to affect the exposure and the white softens the light. I think the material was about $14.00 and the labor was about $15.00

Benji, I am such a visual person, I need to see what you are talking about. It makes sense, I just can't picture how to sew it together.
I did try covering half my softbox with black fabric to get more narrow vertical light and it worked pretty well, but I think I was getting the same effect by turning the light. You know how you turn it a bit to feather the light? Sometimes I turn it more to give a narrower beam of light, I do have to turn up the power a bit when I do that.
