Have you stitched with 12 weight thread yet? Here's a great set to try.
Sulky packaged up six 50 yard spools of 12 weight cotton thread to go with our chart 123 Stitcher Street HERE. I used just one strand of this heavy weight thread on 32 count linen and it looks great.
Because this is twisted thread and not separate strands of floss, it works best if you use it as it comes off the spool. The simplest way to remember, is to pull off just a bit and thread your needle while the thread is still on the spool, pull off the length you want to use, and then cut the thread from the spool. That way, your needle is at the correct end of the thread, which keeps twists and tangles at bay. Just like with floss, you may need to let the needle dangle once in a while to relax the thread.
I love this collection so much, I designed another piece that uses it, HERE!
