Thanks again
@Ann and
@BrendaP - yes, Ann you have got my drift...but....I have no contrasting fabric to make bias strips, that wouldn't be a problem to me but don't want to choose some fabric on line at a cost and find out it wasn't quite right etc. I doubt if our local fabric shop would have something suitable...only school fabrics and bridal there but worth a look in....it's a very small shop and I hope they have a one way traffic system in it.
Yes, Brenda - satin ribbon, non bias although the hem is not curved as such I wondered how it would sit....hence the wee trial which I haven't done yet. (Making a mask for my granddaughter as her father is here working with his Dad...and would like to send it home with him - haven't made this 'origami' one before so it's being done alongside watching how on YouTube!)
Thank you both for your input....it could well be that this dress may not be ready before the weather breaks but however need to finish it for completeness sake.
