When crocheting a granny square with more than 1 colour and it says
Rnd 1: blah blah blah. Join with sl st in the top of beg cluster
Rnd 2: join new colour with sl st in a ch-sp. Blah blah blah...
How do you secure the old colour? I have just been doing kinda like another chain that I pull through quite a lot and then snip but this leaves a little bump bit sticking out. And then i join the new yarn seperately.
The bump doesnt really bother me but if there is a different way i should be doing it then that would be nice to know.
Thanks!
