Spoonflower organic knit fabric

I was so excited when Spoonflower had their annual free shipping day just when I was wanting some neat knit fabrics to make tshirts from, and I ordered two fabrics for me, and one for Hazel, all from Andrea Lauren. I was surprised how thick the fabric was when it arrived, although I suppose I should have been able to figure that out from the weight given for the base fabric. Anyways, I washed them (the ink was very stiff and had a strong smell) and made them up and they look great at first glance but I have some real issues with how the fabric behaved after that which is super disappointing.

I mostly sewed them using my overlocker and despite having ballpoint needles in, and never having this issue with any other knits, the fabric developed little holes where the needle went in. Here you can see it along one of the side seams. It's almost like the fabric is brittle, in that where it's bent back on itself the stitches have cut at the fabric, along with the hole caused by the needle going in. It's not all that obvious when the seam's not pulled back, but I don't know how long until it looks really tatty. The first wash didn't make it look much worse so I'm hoping for the best.

Here it's happened particularly badly at the thick point where the shoulder seam meets the neck binding. The crappy stitching is my machine catching on the seam, can't blame that on Spoonflower! You can also see how it's pulled at the stitches along the shoulder seam.

And then to add insult to injury, I discovered that I'd managed to miss a giant slub in the fabric - and placed it dead centre on the front of course.

So yeah I have a couple of cute tshirts that are wearable but I definitely won't be buying the organic knit fabric again. Anyone have experience with the woven fabrics? I bought some tea towels on the linen/cotton canvas that I'll be curious to see after they've washed.
