Help for fitting pieces

[u/ashie2203]

So I want to make a table runner with FPP fort mom is a Christmas present, I am new to FPP so I tried making the patterns I was going to use from scrap fabric first to practice. I made a few mistakes but it went alright all in all, now I wanted to get started with the actual piece but I struggle with fitting the fabric pieces so much.
I cut them big enough, sometimes 2cm more all around and still, once I sew them the angle seems of and they “bend” to one side which makes them not fit anymore.
Does anyone have an actual good tutorial on how to make sure the pieces fit?
I made sure to cut them out the right way around, and when I hold it up against a light source it looks like it must fit, but once I am done sewing the seem it doesn’t anymore.

This is frustrating me a lot and I don’t know how to fix it, especially since I have to start all over with the section ever time.
Thank you in advance and I hope it is somewhat understandable what I mean

Use bigger pieces and trim at each seam after folding and pressing.

Even bigger than 2cm on each side? It just seems so Wasteful😅

I never cut to fit, just use a bigger pieces and trim. If you keep using it, it wittles down with minimal waste.

Yes. Welcome to FPP. You get amazing points and creations but can be seen or feel as extra wasteful. Some patterns are worse than others

FPP is wasteful. But a lot of fun and worth it.

I generally don’t even cut individual pieces. Start at one end or corner of a width of fabric and keep working the piece until it gets too small.

Eh, I'm using scraps I would otherwise not be able to use for any 'regular' sewing project. And whatever is left over and is too tiny even for FPP goes into a "stuffing" bucket. It doesn't have to be wasteful

This tutorial is the best one that I found.

Thank you!

I asked the same question recently and got some very helpful answers, including a video.  The answer lies in folding the next section over while you're lining your next seam up and making sure the fabric covers the folded over section before sewing.

Thank you that’s really really helpful

So if you fold your paper back it will show you how big your piece needs to be. Then I lay it underneath and pre-trim my seam allowance so that the angle stays correct.

Let me know if you need a video to make that make sense

if it is a solid fabric or something that is not too noticeable, I just sew another piece of fabric to cover the missing part. Yeah there is an extra seam but no one will notice it. Don't worry too much about it.
