I did stoop to pink for the thread that I used to gather the ribbon. I did this for a purpose though as it is easier to see in the photographs.
Decide on the number of petals that you want. I used 5. The more petals, the bigger the hole that will be left in the middle to cover up with a button or a stamen of some sort. You'll see what I mean as we progress.If you decide on 5 petals than the length of ribbon used to make each petal should be 2 1/2 times the width of the ribbon. Yes maths!Made simple
Ribbon = 16mm
Length required for each petal = 40mm
5 petals = 200mm or 20 cm.
Leave an extra cm or 2 for the folding over of the edges. You can always cut off any excess but you can't get it if it isn't there.
So you will need a piece of 16mm ribbon that is about 22 cm long.
Place the ribbon on the table in front of you. The side furthest from you is the inner edge and the one closes to you is the outer edge of the flower.
Mark the ribbon into sections on the inner edge. On a 16mm ribbon these ehould be every 40mm.
Using a running stitch sew along the ribbon as shown in the photograph. Remember to loop the thread over the outer edge of the ribbon when you get to the top of each section. Sew your 5 sections. End with the thread at the outer edge of the ribbon.
Start to pull the thread. You will see the ribbon curl up in front of you. Don't panic. Keep on pulling gently until the petals emerge. The reason for looping the thread over the ribbon is that it pulls the petal into the centre nicelyYou will end up with this curly mess that you see below. Tease it out and you will see the petals. Make sure that the thread is pulled as tightly as possibe without breaking the thread so that the gap in the center is as small as possible. The two inner edges of the flower should be brought together and stitched to hold them in place.
