I did some sewing this a.m. using The Angler. It took me several minutes to get everything lined up exactly right; I then taped the plastic Angler to my machine bed with blue painters' tape and I sewed first a scant 1/4" seam and then a diagonal end (same principal as diagonal corner for Flying Geese or Snowball) and both worked fine.
It's worthwhile to take the time of placing it exactly where it needs to go and taping it on if you want to use it for a lot of diagonal sewing, i.e, chain piecing. As a 1/4" seam guide only, however, your strip of tape on the machine bed should be just as useful and less awkward or, if you need a "bumper" as a 1/4" foot has, you can use a portion of a pad of Post-It notes as a guide.
