It takes forever to bead a spiral when using tiny beads like these. That needle is an inch long quilting between and the spiral will be 5 inches across when complete. These aren't exactly delica beads I don't think but similar. I got them from my favorite bead shop in Eau Claire, WI and I believe they were antique Czechoslovakian ones. They are not uniform in size and I'm struggling with spacing, but basically it is just taking a long time because they are so small. I spaced them out in a different section where I was doing small spirals, but with gaps one loses the spiral altogether. Fortunately, this is the only large motif using these. If it does not use up all that I have, I'm considering filling in the gaps on those other spirals with more beads.
