I am a stockist of these wonderful silk ribbons which are hand dyed. They make the most beautiful life like silk ribbon embroidered flowers and of course are the recommended ribbons for all of Di van Neikerk's publications such as 'Ribbon Embroidery and Stumpwork'.
They are available in a range of widths from 2mm to 7mm although I do have some in 13mm, 25mm and 32 mm.
I have put them in my shop but you need to contact me first with what your requirements are before paying for your ribbons.
