That might be the case.
真布 does not return any results anyway (except for towns name).
On the contrary, 裏布 is a thing, google tells me.
My main problem is that I do not know the vocab related to quilting (in any language, for that matter)…
That being said, either your screen is way better than mine, or your eyes are…
So, not main fabric, but backing fabric, meaning パネル will be a pre-printed main/front fabric, plus fabric for the backing and a third fabric for the bias tape/binding! Good sleuthing, Kyasurin!
I am enlarging that picture on a laptop screen - could not see a thing otherwise! 
Also, I have some experience with sewing, if not quilting.
I think the ribbon comment says
スーちゃんの帽子(ぼうし)のリボン Sue-chan’s hat ribbon
刺しゅう(ししゅう)リボン等(など)で
飾る(かざる)とかわいい
It’s cute if you decorate with embroidery ribbon etc.
Ah! Yeah, now that you say so, I can see it now.
You mean with some kind of magnifying tool, or just clicking the image? (I can barely make it with the “clicked” version)
I have a touch screen… so easy to expand it once clicked. (It’s still hard to read! I am working with a handwritten kanji search tool https://kanji.sljfaq.org/ and some educated guesses.)
Oh, wow! I was at my desktop when I first commented on this thread, but now (on my tablet) having read your comment I just clicked and opened it in a new tab, and SUPERZOOM! If only my Japanese could be so easily improved…
Under 全てカラフルに
端切れ(はぎれ)で with odds and ends (scraps of cloth) 充分(じゅうぶん)作れます you can make it sufficiently
I think the next line is ??色で楽しみましょう
Is it 色々色で。。。 If so, how delightful!
I don’t think so… but still trying to figure out the first kanji!
EDIT: found it! 配色 はいしょく colour scheme
We’re in the same time zone, but it’s well past my bedtime, so おやすみなさい。
That looked like 2 characters, not one - well done! (really must go to bed…)
Thanks for the input everyone! It was great practice on my end as well!
Here’s just one more page (split in to two):
I wonder if I’m even better than google translate, but here goes.

Way of making it
Copy the bottom drawing on the front side of the foundation cloth and do applications in order.
Make a mark on the front side of the application cloth that goes on top, leave a sewing margin of 0.3 cm and cut.
On top of the applied cloth, it’s not necessary to apply where the next cloth will be.

Kit content:
* thread
(no orange circle available 
)
There’s no quilt cotton inside.
The fabric was selected to be as close as possible to the specimen, but since the kits are made from recuperated items, there may be some small differences. Thank you for your understanding.

Nath you a legend, but we need to introduce you to some fundamental sewing terms!
アップリケ: An appliqué is ornamental needlework in which pieces of fabric in different shapes and patterns are sewn or stuck onto a larger piece to form a picture or pattern.
刺しゅう糸 is embroidery thread (different to regular thread)
Yeah, I figured I was going to get things very very wrong. I am learning a lot 
baby kilt
I googled 落としキルト
ピースワークやアップリケをした縫い目の際にするキルティングのこと。表から見えないようにキルティングをしますが、モチーフが浮き上がって見えるので、陰影を出す効果があります。
So it seems you outline the motif without the stitches showing.
I thought of mentioning a couple myself, but I’m actually having a hard time ('cause my Japanese bites the big one) of understanding the gist of some of this (plus OP might not need my ‘translation’).
Sewing margin = seam allowance
quilt cotton = cotton batting / quilt batting / wadding
That said, there are dialectal differences within English - my Aussie teacher kept talking about ‘cotton’ or ‘sewing cotton’ - took me an AGE to realise she meant ‘thread’!
Edit: She calls it this even when the thread is polyester!!!
@JessDoubleThink I found a couple of pages with Japanese sewing terms, these may be of interest to the lady who gave you the documents to translate, if she regularly gets materials from Japan.
www.japanesesewingbooks.com/japanese-sewing-terminology-a-list-of-translated-terms/
Yes, this is what i grew up with! I guess the materials change faster than the language. The same way we still “hoover” while using some other brand of vacuum cleaner.
I followed your link and quickly saw the list is origanlly from a French blog - I can see you are determined to transform Nath into a trilingual fashion designer!
