Just a few strange quilting tools to share while I'm thinking of them:
June Tailor Shape Cut- Great for cutting strips of fabric, this 12x12 ruler has slots 1/2 inch apart for cutting straight lines without having to keep shifting the ruler. It is also great for when you want to cut a certain measurement away from a cut edge, like along a selvedge. This wide ruler allows you to measure from the edge with the majority of the ruler on the fabric, as opposed to placing a regular rotary cutting ruler off the edge of the fabric, making it a bit unstable as you cut.
Related to my post about being a bit obsessive with straight grain, is my laser level. It helps me get a good straight line for long cuts, for blocking a quilt, and to make sure a design on my design wall is straight and square. My old house is very cozy and unique, but level and square it is not in places, so I've learned not to eye-ball anything in relation to the floor or ceiling! I really want to get a pair of tile laying laser squares for better squaring up of quilts; they project 90 degree angles!
Finally, everyone should be so blessed as to have a great helper and cheering section for their quilting! This is my daughter watching as I put some decorative stitches onto on of her projects we made together. Beautiful, isn't she?
