Okay, okay, so a long time ago, I already asked about prewashing fabrics. I'm not going to lie, I can be super slack on that. BUT--I really want to be more diligent because I'm going to start sewing for my sister's baby (not born yet!) and would like to make everything as nice and clean as possible. However, the thought of washing all the fabrics I have at once terrifies me. I've been doing some research, but I still had some questions..
So. If I need to wash like a pagillion fabrics that are between .25-3 yards, how do I? I do NOT want to individually wash them! But I'm super paranoid that some fabrics will bleed on the others! I would absolutely love to just dump all of them at once into the washer, but that's not reasonable. Washing individually is terribly uneconomical, and I would like to avoid that. I feel confident about some fabrics, and am pretty sure they won't bleed, but there are some that I don't feel comfortable with. However, I also feel even less comfortable devoting a whole wash for like .25-3 yards (and then all that time included!).
I've read a couple of suggestions. First, perform a bleed test. Did that. It sorta bled? Like, I had to rub the crap out of it onto a washcloth to see a very slight color transfer. Do you think it's safe? It's really blue, with a lot of hot pink (the fabric, not the bleed)... D: What would be considered a dangerous bleed? Like, bleed on contact, or bleed when rubbed??
Then, I read about setting dyes/removing excess dyes chemically. There is Synthrapol and Retayne, which I would have to go out and get (yo, I'm a slacker who doesn't like spending money unless it's absolutely necessary...or fabric ). But, I also heard of setting/removing (don't know which?) with vinegar or salt. I read to soak in salt water solution overnight--but the ratios were vague. Does anyone know about this? And another method: to use a 1:3 vinegar+water solution--but to wash, or to soak? How long? How do you rinse the vinegar out well enough?
And then finally, the one thing that I sounds the most promising to me: washing in pillowcases (or other sack). I figured, for fabrics I'm not so sure about, I could just pop them in a pillowcase..right? But then, problem comes: can you really adequately wash up to 3 yards of fabric inside a pillow case? Would that be counter-effective? And, would that actually work to prevent any potential (mild/slight) bleeding on other fabrics?
And extra finally, am I thinking way too hard about this? Is this generally not that complicated? I mean, I don't think this hard when I buy new clothes or linens (which often shrink/bleed after washes). I'd rather not ruin a bunch of fabrics at once, but I really, really do not want to spend forever washing them individually and wasting loads of laundry! I would definitely be open to washing smaller pieces (under a yard) by hand, if that would work. Except, I still think up to 3 (or even 5) yards alone in a wash would be a waste. And then, I'm worried if it would properly preshrink!
I'm so sorry this post is so long! I just don't have anyone to ask these questions, and I get so paranoid that I become paralyzed in fear of messing up. Thank you for any kind of help!
