I love how the colors are so bold and bright, and they really tie in together...oops, tie in....I guess pun intended...lol...I have tied a few quilts, I like them, too...As far as you trying to machine quilt...this quilt would be a great one to start with...you could stitch a 1/4" away from the seams, using your 1/4" foot as the guide...it is just straight stitching, just like sewing....I know that some people say to use a walking or even feed foot for this type of quilting, and I have done that...but, I have to say that my lqs leader said she never uses the special foot, she just uses her 1/4" foot...I tried it, and it worked fine...anyways, will look great whatever you decide.
