OK, here are some pictures of the fabrics and trims I still have.
The second picture shows how thin they are. Very! I put them both into the washing machine right now, just in case, remembering the 2.0 x 1.4 m of linen knit that came out after washing as 1.5 x 1.1 m, all for the fantastic price of almost 50,- ?.
If you would like to take a look at picture 1, you can see from top to bottom:
1.) tacky poly lace, white, a bit stiff, about 3 inches/ 7 cm wide, got 5 m/ 5 1/2 yards of it. The question is: will the stiffness go with washing as tulle tends to get softer? Can the lace be dyed? If so, which colour?2.) Satin bias binding, not much of it, perhaps two meters. Doesn't really go with any of the two fabrics but doesn't slap you in the face, either, if you know what I mean.
3.) elastic lace, 18 cm/ 7 in. wide, might go with the darker of two fabrics as an insert around the midriff. Would need to get matching bias binding for the neckline perhaps.4.) Broderie anglaise, ca. 7 cm/3 in. wide. Definitely dyable; again, which colour? Could be fitted with satin ribbon.
I'm pretty certain about the burgundy elastic lace; that might be used, but I'm afraid I'll have to get something for the paler pink stuff. Dang, and I had hoped to get rid of some of my stashed laces... ;-)
U. - input very welcome!
