I like most applique styles but have not tried a large Hawaiian (don't know why - they just don't appeal) and I prefer to work by hand on most of them. I have my own method for doing applique onto pre-quilted fabric, so I spend minimal time at the SM. I've done album-style blocks, picture blocks, Celtic knots and abstract shapes onto prequitled fabric, and I don't think I will ever go back to any previous method I have tried for large projects.
Current project is a 6' Jacobean Tree of Life. I think I will experiment with padding the applique, just to see how it looks. I hope to put a totally different applique design (abstract cat figures) on the reverse.
I love to start with a design and then modify or develop it and see where I end up. Some of the finished designs are unrecognisable from the starting points. I recently broke a Celtic knot border down to interlocking "S" shapes just over
1" wide, which made the placement and applique much easier, and virtually eliminated marking.
Unfortunately I enjoy the experimentation far more than the repetition required to complete a project - hence the UFO pile lol
