I have 2 Pfaffs - Quilt Expression and Grand Quilter and they are just fabulous. They are set up in my room and don't move - they are very heavy. So for classes I bought a Janome Jem - fine for carrying but the seam allowances don't match up. Anything I start in classes I either have to finish on the jem or start again on the pffaf. Last class I used scraps and uglies as samples and did all the stages of the pattern - New york Beauty - and then cut my batiks to work on at home. That worked very well - no waste, well hardly any! It me a few attempts to get the idea of foundation piecing in class and I was very glad that wasn't my precious batiks. oops sorry I've gone on a bit!!
