Can someone check my calculations please..

[Flooz]

Having (another) confidence crisis.

Track is 2395mm
Total flat width of fabric is 5040mm (it was 5 widths but I lost so much in pattern matching it's probably nearer 4 now )

I've allowed 130mm for ease (hope this is enough).

allowing for 18 pleats (which will be double pleats), i've ended up with 139.7 for each pleat and 132.8 for each flat (19, I believe it should be).

Working my calculation backwards, it does total (within a couple of mm's) back to the total flat width of fabric.

Have it done this right?

Many thanks for your help.

mmm, well something isn't right. I've just pinned my markings, and the middle edge - which I believe should have 'half a flat' measurement, has got more than that - almost a whole 'flat'. So, where have I gone wrong I wonder??

Re: Can someone check my calculations please..

it's ok - i'd measured my fabric wrong, it seems to be working better now. Although I still had slightly more than a half 'flat' on the centre edge. But that may well be as a result of all the 0.8 of a mm in the calculations.

I shall post a picture once they're completed (if i'm happy with them once they're hung that is).
