I learned a technique from Ro Mead where you apply the slip to fabric, wait for it to set up just right ... then gently press it onto the surface. The success depends on waiting for the right moment ... Too soon you just get squished messes ... Too late it cracks. We used old cotton bed sheets which tend to wick off excess moisture at an even rate. We drew our patterns on the reverse ... they showed up through the fabric so we could easily apply slip. Just wash and reuse.
I wonder if a similar technique could have been used with glaze on bisque in the Calico Glazed Mystery I posted a few days back?
Good that you kept a stock of clean bed sheets for new work, or for attending KKK meetings.
