I made those two scarves using soluvlies, a water soluble interfacing.
I love the technique: you simple put some fibers (or fabric and lace stripes in my case) between two layers of interfacing, arrange them the way you like, stitch through the interfacing and fabric and then you wash out the interfacing - then you have a beautiful scarf (or any item of clothing, actually) made of fabric stripes
Here's the first scarf I made in all its beauty:
And with the interfacing:
The 2nd scarf:
I took photos of all the steps when I made the 2nd scarf, so here's a short (but image heavy) tutorial:
Prepare your fabric stripes (I ripped them, because I wanted them to look frayed and organic)
Cut the interfacing to the shape you like your scarf to be, arrange the fabric stripes on it:
Cover with a new layer of interfacing, pin at a few places to secure:
Start stitching! You can draw a pattern and do this neatly or go wild like I did:
Wash out the interfacing using water, rinse at least twice. If you feel that there's some of the interfacing left maybe use some soap
Put it onto a large towel to dry
And that's it =)
If your finished scarf feels stiff/hard there's probably some interfacing left, if you don't like the effect wash it again.
