    I love your videos they have given me the confidence to make my own curtains and blinds....Julie

    Your videos are so good, thank you…..Alex

    Once again, I should say that I think the video tutorials are extremely well done. Although I've been sewing for years I've learnt lots of techniques that are new to me and that give a much more professional finish........Heather

    Thank you for such brilliant tutorials and videos....... ....Barbara

    I have absolutely loved your videos for curtain making, I have learnt so much from you….Charlotte

    Step 9: Form the Pleats
    Printable Worksheet
    Printable Instructions

    CALCULATE YOUR PLEAT SIZES & SPACING

    Measure the width of your unpleated curtain panel.(PAN)

    To do this we already know:

    • The finished width of the curtain (FW)

    Now Choose:

    • The width of your RETURN* - we recommend 8cm. (R)
    • The width of your LEADING EDGE - we recommend 8cm.(LE)

    *Note if you are returning to the wall make this the distance from the pole to the wall plus 1cm.

    Next

    1. CALCULATE WIDTH OF FABRIC AVAILABLE TO FORM PLEATS (WFP)

    To calculate the width of fabric available to form pleats simply subtract the Finished Curtain Width (STEP 2) from the width of the panel to be pleated.

    • WFP = PAN - FW

    2. DECIDE THE NUMBER OF PLEATS (NP)

    You now know how much fabric you have to form pleats (WFP). Next you need to decide how many pleats you want your curtain to have (NP).

    <

    As a guide if you have been working with our recommended fullness ratios, we would usually look to use the following number of pleats per width.

    • Double Pleat 5-6 pleats
    • Triple Pleat 4 pleats
    • Cartridge Pleat 6 pleats
    • Goblet Pleat 4-5 pleats

    For example if you are using 6 pleats for every fabric width used to make the curtain panel and you have used 2 widths of fabric to make your panel we would recommend 12 pleats, if you have used 1.5 widths we would recommend 9 pleats etc.

    3. CALCULATE THE ACTUAL PLEAT SIZE & SPACE SIZE

    PLEAT SIZE (PS)

    To calculate your pleat size divide the fabric available for pleats by the number of pleats.

    • PS = WFP ÷ NP

    SPACE SIZE (SS)

    You will always have one space less than the number of pleats. For example 12 pleats - 11 spaces, 10 pleats-9 spaces. To find the size of the space between pleats

    • Subtract the size of the RETURN and LEADING EDGE from the finished curtain width
    • Divide the result by (the number of pleats minus 1)
    • SS = (FW - LE - R) ÷ (NP-1)

    You should now know

    • The width of the fabric panel to be pleated
    • The number of pleats per curtain.
    • The size of each pleat
    • The space between each pleat
    • The size of the RETURN
    • The size of the LEADING EDGE

    CHECK YOUR RESULTS

    If you are new to curtain making, fold a sample pleat with some buckramc the size of the pleat you have calculated (see STEP 9b - How to fold the Pleat). If you are not happy with size of pleat and the space sizes start the calculation again using a smaller number of pleats for a larger pleat, or a higher number of pleats to make your pleats smaller.

    MARK OUT AND SEW IN YOUR PLEAT SECTIONS

    • Lay the curtain down, right side facing up.
    • Mark along the top of the curtain where each pleat will start and stop with a pin
    • Check the size of your RETURN, LEADING EDGE and the spaces between the pleats add up to the finished width of the curtain.
    • With a vanishing marker draw a vertical line down from each pin to the bottom of the buckram to mark the edge of each pleat.
    • Remove the pins
    • Pinch the back of each pleat together so the lines match up.
    • Machine stitch down the line to the bottom of the buckram (to hold the back of each pleat together).
    • Once you have sewn in all the pleats check the width of the heading is now the finished width of the curtain.

    Hi, loving your incredibly helpful tutorial.

    I'm making quite heavy interlined curtains for a draughty bay window. Because of the sheer weight of the total fabric, the price and the work involved, i've gone for quite a low fullness ratio - it'll be 1.6 or 1.7 ish. I'm wondering what kind of pleat would be best under these circumstances. Or would it be best to use heading tape? Have you got any advice? Thanks!

    With a Tab top or eyelet heading you can get away with a less fullness, but this wont work in a bay.

    Pencil pleat (heading tape) does not look good if the fullness ratio is less than 2.2.

    Hand pleated -the pleats will be small and the gaps large with that fullness ratio. Interlined curtains due to their bulk do not make up well with small dainty pleats.

    We would not make up with those fullness ratios. We think  you need more fabric. When cost is an issue we always recommend going for a cheaper fabric but making up well. We never skimp on the fullness of fabric.

    Belated thanks for your response. Just finding the mental energy to get back to curtain making!! More fabric it is then...

    Thank you so much for your great tutorials. Are you using a walking foot when you sew the pleats?
    Sew Helpful
    Yes I am in the videos, you don't have to use one, but it does help with slippage between the layers.
    Jennifer
    Should the return and the leading edge always be the same amount?

    My pole length is 360cm do you still recommend 8 cm for this length of pole?

    Thank you

    That’s how we do it, you can vary it but the longer you make them the flappier they get.
