if I allowed 5 cm for head rail allowance in step 2, what width should this batten be - 5cm exactly ? thank you
No the headrail allowance takes into account not only the depth of the
batten but also the eyelets underneath so there is enough room for the
blind to pull up under the batten. That is why 1.5 times the depth of
the batten is recommended with a minimum of 5cm. If you use a batten 5cm
deep the blind would not pull all the way up.
can you advise on exact dimensions of the headrail batten, i made an allowance of 5 cm in step 2. thank you.
The wooden head rail batten we use in the workshop is 18mm by 34mm. If
have only used 5cm as a head rail allowance I would use the 18mm face to
attach the Velcro (hook tape) to, to make sure you have enough room for
the blind to Pull up under the headrail.
Thank you ! I was wrong actually as i see my headrail allowance was 8cm, so i guess a wider head rail will work.( 5?) I am now a bit confused as seem to have an awful lot of fabric left above my last rod. ( FBD 170, 4 rods, folds of 18cm, top one of 26.) this was done with your calculator. I will measure exactly tomorrow as am not in my work space now.
Have you got 44cm of fabric from the top of the blind down to the first rod?
18cm +18cm +8cm headrail allowance = 44cm
I am about to sew the velcro onto the heading of my Roman blind..would you recommend a particular width of velcro? My blind is 180cm drop and I am wondering if my 2cm wide velcro is adequate or should it be wider? Thank you
The standard tape width is about 25mm and that is what the hook velcro
will be on the rail. We have made all sizes of blind using 25mm in the
past and it has been fine. That is what our tutorial and videos are
More recently in the workshop we have switched to a 50mm wide hook velcro on most of our blinds as it helps with positioning the blind and gives the heading a little more stability. We will be including information about that in our new improved tutorials and videos we are making now.
Is there any need to line the batten if it can't be seen inside or out? (Will the velcro stick directly to the wood?)
You do not need to cover the batten with lining to make the blind work,
it just makes it look neater and more professional. Some people paint
the batten to make it match the surroundings. If you choose to not cover
it, it will still work fine. We staple the velcro as well as stick it
to make sure it holds.
