I think back to some of the pots we made when we first started our pottery, and they were pretty awful pots. We thought at the time they were good; they were the best we could make, but our thinking was so elemental that the pots had that quality also, and so they don't have a richness about them which I look for in my work today. Whether I achieve it all the time, that's another question, because I don't think a person can produce at top level 100 percent of the time.

Here is this ability to explore ideas, but with minute changes, and then look at the results. Often you get so excited about what you're doing that you think, "Oh, wow, this is just great." And you look at it a week later and you realize you'd been excited by the act of creation, but what you've created is not really exciting when you look at it in cold blood. And so that, to me, is a valuable lesson also.

Some years ago I was working on some forms which were vase forms with a fairly narrow base, and it was after [Hans] Coper had died that I saw an exhibition of his, a catalogue from an exhibition, and he was showing some forms which were made by cutting and joining a lot of different parts together to create what he called a spade form, which you can imagine looks a little bit like a shovel upside down.

We thought [with Alix MacKenzie], if those are the kinds of pots from every culture that interest us, why would we think that it should be any different in mid-North America 20th century? And we decided then that our work would center around that sort of utilitarian pottery, and that's what I've done ever since.

Eventually I gave up teaching at the St. Paul Gallery because of disagreements with the philosophy of that museum, and I got a job at the University of Minnesota, which was very fortunate because it was a part-time job and that gave us a great deal of time in our studio to work together and to make the pots we wanted to make.

In working on a drawing or a painting, one can rework and rework and rework and change ideas until you get it the way you think is right at that time. With clay that's not possible. You either succeed the first time, or you should wad it up and start over again, because you can't mess around with the clay and still have it fresh.

That [silk-screen process experience] carried over when I returned from the Army and took more graphic classes at the Institute. And Alix [MacKenzie] and I actually began to produce a line of textiles, which had silk-screen patterns on them.
