Here is a small sample of some of the lovely threads you can use to create different textures.
Cotton – 6-stranded such as DMC or Anchor; can be separated into 1 or more strands.
Perle cotton, comes in different thicknesses, with the higher the number, the finer the thread.
Silks – floss silk such as Madeira. This is untwisted with a high sheen. Can be separated into 4 strands.
Synthetic threads – come in a smaller range of colours than cottons but are shinier.
Metallic threads – come in different thicknesses, but thicker threads need to be couched, as pulling through fabric causes them to splinter.
DMC threads have have a great website at http://tinyurl.com/lehgvg, it is well worth a browse.
I have just had an article published at http://tinyurl.com/njryhs - hope you enjoy it, it is a lighthearted look at learning about patchwork and quilting.
