I have been using DMC Fil and been asked what is it? This one is a single ply metallic similar to blending filament but a tad bit wider. It is also a bit sturdier in the needle. It comes on a spool and this pattern has used single and double ply so far.
Today's progress report! The last vertical column on the right has Sprat's Head stitches worked in 1/16 ribbon first. Then between those are backstitches with another color of 1/6.
The triangles are tri-layered. Perle 5 was stitched diagonally across each one. Then Marlitt was stitched over the top of those from the other angle to create padding. Finally Sprat's Heads were worked in a single ply of DMC Fil over the top of those. Very sparkly!
