Here's my half square triangle Tree Quilt. The designs in the fabrics include cross-sawn tree trunks, tree branches, flowers and woodland animals. The large yellow square block has quilting intended to look like tree bark and a reverse circle imitating a hole in the "trunk."
The quilt has a wool batting. It has a lovely, light loft and quilts beautifully.
I initially just quilted the diamond pattern and the close quilting in the yellow block. The quilt seemed to float. But I decided that the quilting just wasn't close enough for use over the long term. So now each of the half square triangles has quilting outlining it. It doesn't have the quite the same floating feel now but still is a bit puffy.
I'm really pleased, however, that the diamond pattern of the quilting is still what draws the eye. I think that's due the layout of the blocks and to the 2 lines of quilting 1/4 inch apart alternating every 2 rows of blocks in the quilt.
This is a happy fall quilt and I really look forward to using it on the chilly nights which will be here soon!
