I am not a follow the rules kind of sewer; sometimes I don't pre-wash my fabric, I don't like making muslins, I use the word sewer instead of sewist (badass, I know). This is why it's all the worse when I try and do everything right and it still doesn't work.Let me start at the beginning. I saw the fabric in Spotlight and I had to have it. It was the perfect weight and print for a Spring coat. I knew the perfect pattern to use. Simplicity 1411. I wanted three-quarter set-in sleeves so I redrafted the pattern to have those. I made a muslin. I kept faithful notes of all the changes I made to the muslin. I pre-washed the fabric.
Everything came together perfectly until it came time to do the buttonholes. I noticed a tiny stain on the fabric so I put a little bit of stain remover on it, rinsed it off and then washed my almost finished coat. I have used this stain remover heaps of times, even using it on my precious vintage dresses and it's been fine.
When my coat dried the blue dye had run in several places all over the white dots. It's strange because it ran in places that were nowhere near where the original stain was.
It doesn't actually look that bad in these pictures but it's pretty noticeable in person.
So, now it sits on a hanger in my sewing room. It's too stained to bother finishing it but too pretty to just throw away.
Moral of the story: don't be seduced by cheap and pretty fabric from Spotlight.
