Yes it does matter, we would throw it away and start again in the workroom. Cutting a lining panel with straight parallel sides and a straight square bottom, is crucial for making a well made roman blind. If you don't get this bit right you will find ..........
We never use tape in the workroom, as we believe pockets made from the lining and sewn on brass rings give a far more professional finish. We also think it is easier to neatly sew a rod pocket than sew the tape on.
On the plus side for tape, it does reduce the work later as you can use the tape fabric loops rather than sew rings on to guide the cords and clip safety breakouts on rather than sew them on.
Of course if you have a kit where the safety breakouts are clipped on you will have to use the tape provided.
Thank you for these wonderful tutorials, calculators and videos. I am a novice sewer but hope with the help of your well structured and fully comprehensive guide throughout each individual step, I’ll have the confidence to successfully complete a Roman Blind.
