I have quilted out this pattern several times now -- at about 18" high. Took about an hour & a half to go across a queen size row. Obviously it falls into my highest pricing range as I consider this 'semi-custom'. This design is stunning !! I used a varigated Polyquilter thread on the back. The shop has gone crazy when they saw it as some of the fabrics in the one quilt top were mums and on the plain backing, this design complemented the quilt top exactly. You won't go wrong with this design - but it probably isn't going to be one in your 'bread & butter' category !! :) Bona Longarm List @ www.quiltropolis.com
I've used this lovely design several times now, and it stitches up beautifully. It's a fairly dense design, and it's definitely not a quick one to stitch out. I've stitched it out at various heights between 18"-20", and that worked very well.
I used this pattern in gold metallic thread on an Asian quilt. It took a LONG time, but it was beautiful. Don't try to reduce it...unless you have a lot of time!
