I few weeks ago I put on a multicolored pearl cotton warp for 9 baby blankets. These are blankets I have been weaving for years, and I always enjoy weaving them. They are kind of "design as I go" blankets, and for that reason it takes a little while for me to get going with them once they are on the loom. So... they stayed on the loom for about three weeks before the weaving began.
Tip # 2: Selvedge Control. When weaving plain weave with two shuttles it is important to interlock the weft yarns to get neat selvedges. Positioning the shuttles correctly is the key. Pay attention as your shuttle exits the shed. If the edge thread is up, place your shuttle near the fell of the cloth. If the edge thread is down, place your shuttle near your body. If you do this, the wefts will always interlock.
When the blankets are done, I will post pictures of them in the Gallery.
I have been happily weaving since my son was born in 1988.
