When to block pieces, before joining or after?

[rissaroo1234]

 

So I'm working on making a small purse. I have a few rectangle pieces that I will be sewing together with yarn and a yarn needle. The corners are curling a fair amount, so I want to make sure I block them all.

My question is, is it better to...

A) Sew all the pieces together, then block the entire thing

B) Block all the pieces individually, then sew all the pieces together

C) Pin the pieces together, block while pinned, and then sew pieces together. 


Also, if it makes a difference, I'm using Red Heart Value yarn. So the basic and cheap worsted weight yarn made of acrylic. Its a bit rougher and has a little more of a ridged drape then other nicer but more expensive yarns.

And while I'm here asking, if you could also tell me what the best method of blocking to use would be, that would be great!

Thank you!

I find that Red Heart yarn does not need blocking.  The curling on the corners of the blocks are probably due to not having enough stitches when turning the corners.  After you sew them together, they should be good.

It's a total waste of time to try to block Red Heart.  It won't hold.  Natural fibers like cotton hold a block well.

 

I hope sewing it together is enough to straighten it out.
