Serger thread Question

[Zacharyc]

I recently picked up a baby lock bl3-407. I am wanting to serge some 10oz canvas material. In the back of the book there is some reference  to thread and needle size for heavy cotton cloth material. Here is where I get confused. The book is telling me I need #80-60 thread and a size dc #11 - #14 needle. Don't know what #80-60 thread is? Does anyone know a good general purpose thread and/or needles for this type of canvas work? Figured I'd ask here before I start shooting in the dark. Thank you!

I just buy standard size, but higher quality cones of serger thread at Joann Fabrics, or any other store that sells domestic sewing supplies. I use system DBx1, size 14 needles. I could move down to #12 needles for tighter holes, but see no need for it. Test both sizes in a test seam of your canvas.

If you buy extra heavy thread, like size 80, you'll definitely need at least #16, or possibly #18 needles. Size 80 is light weight "jeans" thread. I buy #80 thread, along with #105 heavy jeans thread from Wawak.com.

All of the above mentioned thread is either cotton, or polyester, or cotton wrapped over a polyester core (aka: Polycore). The better quality serger and jeans threads are not as fuzzy as lesser quality brands. It's a good idea to examine the thread on the cones before buying it. The better Q thread cones cost double what the el-cheapo cones sell for.
