I have just lost a reply so doing shorthand version.
I'm doing a class at present with embroidery on top. These are instructions we were given.
* onto paper side of bondaweb trace the shapes you want. Make those which go under top piece a little longer to go under. Use a biro.
*Cut out roughly not on line.
*PRESS the bubble side, paper side facing up onto back of selected fabrics.
*now cut out on the line.
* place all pieces in their places on back ground . I suggest mark with frixion pen location of outer edges.
*now peel off the paper and put this new bubble side on back ground. When they are all I place PRESS, PRESS, PRESS.
don't iron as this will make pieces side about .
* using an invisible thread and using a wide small zigzag go over all the edges. Don't panic if you over shoot.
* embroider the inner edges
*put on batting/ wadding and muslin / think its cheesecloth in US on the back. Pin or tack/baste to keep still.
* embroider the edges and veins etc to make quilt effect.
This is my first block ready to leave now until others done as it is a quilt as you go, we go the class every month .
