Sew, Mama Sew are inviting us to show off our thread stash, so here goes!
I have been quilting for years, and have amassed a lot of this thread over the years. I mainly use neutrals for piecing (ecru, white, black, grey and tan) and stock up on these whenever I come across a good deal. I still have a lot of hand quilting thread from when I first started out, but rarely use it these days.
For machine quilting I use a lot of rayon, but I buy interesting thread whenever I see something I want to try, so I have sliver thread, metallics, cotton, linen - you name it... I also have a lot of cotton floss ( I used to do a lot of cross-stitch) and sometimes use that or perle cotton for hand quilting and embroidery.
I don't always match the colour perfectly to my projects. For backgrounds and large areas I generally go for matching thread, but if I sew a motif that I want to stand out, I might use a contrasting thread, or if there are lots of colours and I'm doing an allover pattern, I usually go for something that goes with all the colours, maybe some varigated thread. I prefer to use the same colour in the bobbin, but I often choose cotton thread if I'm using rayon for quilting.
I store my thread in these little drawer units from IKEA. They keep it dust free, and if I'm doing some kind of machine embroidery or something which involves a lot of colour changes, I can just pull out a drawer or two and bring them over to my sewing table for a little rummage. I have them sorted by colour and type of thread, so it is relatively easy to remember which drawer to look in.
My floss is stored in precut lengths threaded onto cardboard strips sorted by numbers. I keep them in a storage container (also IKEA) and have room left over for a plastic bag with bits and pieces left over from other projects.
I have some single skeins of silk and linen thread in there as well. These are precut and braided so they don't tangle. It's easy to pull a single thread from the braid when I need it.
For embroidery I also have some of these sweet little tins with magnetic lids. The each hold one ball of perle cotton, and the end can be threaded out through the hole in the lid and onto a needle. The magnet holds the needle in place for whenever I need it.
So there you go - I seem to have lots of thread, but I'm always on the lookout for more - how can you quilt without thread, after all ;-)
