Nice quilt! I haven't been brave enough to make something out of a panel, even though I collect them!
I only knew how to SID before discovering this wonderful board featuring a wealth of knowledge and encouragement. Now, painter's tape is my straight line guide. (don't sew over it---ask how I know!) I made a giraffe quilt for a recovery quilt for my cousin in the hospital. I used the 2 inch wide tape and just stitched vertically. here's a pic.
