Thanks to all of you who made suggestions about how to attach fabric to the crochet blanket my Nan made (and thanks to everyone that couldn't help but left nice comments anyway!). I had a go at machining it and let's just say it didn't work out. The blanket's tension isn't great and it was just too hard to control (add in that I didn't baste it very well in the first place). Since it is kind of stretchy I'm just going to blanket stitch around the edges and tie some of the corners of the grannies once I'm done. I'm going for a home made look with this one I think! Should it fall apart or need more work I will just do that as and when.
