Woven or stretch?

Minerva Crafts tends to sell the same fabric in many different shades so you can pick one and get several colourways and be sure they are all the same thickness.

I tend to stash dive remnants for colour blocking, and find things that feel similar weight.  Anything too thin, double it up or back it

I've done some with different weight fabrics, just be careful where you place each piece, for example, I've used heavier near the top and lighter near the bottom.  Although having said that, I did one with the heavier fabric as lower side inserts.

One of the items I made for the stash busting sewalong was colour blocked.  The black and the multi are woven crepes and the red is stretchy knit.  They look OK together and served the purpose of using up stash it would really have been better if the red wasn't so stretchy.

thanks all - would it matter if one fabric was much stretchier than another?  Descriptions on the internet are often very vague when it comes to stretchiness - and even if you order samples it is difficult to judge when you only get a tiny piece

That very much depends on the style, the fabric, and how you block it- you wouldn't want a very stretchy skirt/peplum on a non stretchy top, as it might sag, but the best thing to do is play with some remnants or cheap oddments, and see what transpires.  Knits are so different, it's all experimental
