Sewing knitted patches together

[Zigzagwanderer]

My tension squares are different sizes and varying yarn but mostly similar.
Some are different sizes and shapes (rectangle/square).

Is this going to be a nightmare to sew together?

I will block them but then I have no idea what to do, I need a plan!

Any advice welcomed.

The short answer is "yes".The longer answer is that you can try and match shapes that are roughly the same and make them into strips. Then you can sew the strips together. Lay it all out on the floor and see if you can roughly match it. Then stretch a bit here and ease a bit there and hey presto you have a blanket. Or a cushion cover. Or a bag. Best of luck

Ok I hadn't thought of that, good idea.
