I've managed to figure out most of what I need to produce a pretty skating dress for my daughter, but appliques give me fits of trouble. Dress construction, pattern drafting, dip dying skirts, stoning & beading are all no problem - but I just can't seem to add an applique without it puckering up. I sew on a 30 year old Bernina, which runs like clockwork and holds a consistent tension but doesn't have much in the way of extras. I'm contemplating adding a walking foot - would it be worth the $100? I have tried hooping before sewing and that helps but some fabrics, like velvet, can't be hooped without marring. I've also tried the iron on/tear off stabilizer that was supposed to peel off afterwards. Again, helped but was a bear to get off the fabric later and still wasn't perfect. Sewing with tissue paper underneath just jams up my machine and makes a big old mess out of the bobbin thread.
Does anybody have any tips, links to tutorials, or instruction books? I haven't managed to find something that works with my machine yet. I know it's possible to sew stretchy appliques and have them lay nice and flat because I see it all over the internet. Thanks in advance for any help, I'm really struggling with some flowers right now. Fortunately the puckers sort of disappear when it's stretched from being worn, but I really want to master this technique.
