I have assembled all the edge pieces according to the plan and now need to knit and assemble the trim onto these pieces.
I made a provisional crochet cast on, in a contrast colour, to enable me to graft the ends of the trim invisibly and started to knit the trim directly onto the blanket but I think that it looks a bit messy.
I then thought of crocheting around the edge of the blanket and knitting the edge onto this. I may end up by knitting it separately and mattress stitching it on to the blanket.
My intention is to sew the middle pieces together in strips so that it will mean that once the trim is in place the centre can be stitched in easily and quickly.
