According to this website
http://www.fabricgodmother.co.uk/fresia-viscose-challis-black/
the fabric is suitable for a blouse. It does however, apparently shrink slightly. Viscose can be awkward to sew, I don't mind it but it can feel quite 'flimsy' and some do fray quite a lot. Love the fabric it's a really pretty pattern.

I like this website  as they give free patterns but lots of advice, hints and tips.

Oh that's nice, you'll be able to wear both smart and casual. very useful. I like the fabric too.

I use big flat washers from B&Q they are about 2"square with a hole in the middle and are quite heavy. Not cheap but I've had them for quite a few years now and they don't take up much room.

I've made this twice in the last few weeks

Play Jessie and enjoy it, I'm sure it will turn out fine.

Don't beat yourself up Iminei, the BOM weren't meant to form anything, they were/are tutorials to get us to try different blocks - with VERY good results (not mine). I chose to use the same fabrics because that is what I found at the start. I put them together - on the floor to see what they looked like and took the photo. It's a great big THANK YOU from me because without what you have done I would probably still be doing easy stuff. Whether I put them into a quilt at the end remains to be seen.

Hehe, no eateries at the Birkenhead store - thank goodness.

I'm not going to participate this month as I don't have any suitable fabric, but I'll definitely be back in July.  

I did mine with the same fabric that I've used for the other blocks, no Japanese type fabric in sight.
