I make a lot of machine embroidered free standing lace and have tried numerous methods such as double sided tape on the inner hoop, wrapping the inner hoop with tacky vilene, strong silver tape, long strong quilting pins etc, in a vain attempt to stop the soluble stabiliser from slipping during stitch out. All had their various idiosyncrasies and all were less than perfect at holding the stabiliser drum tight. The larger the design the more difficult it was to keep taught during the stitching out. Then I saw a YouTube video where a designer used T-pins and eventually found these pins on the MSQC web site so ordered them straight away. What a game changer!! They were easy to slip through the stabiliser, right along the edge of the hoops, strong enough not to bend in the process and the T top “locked” against the hoops holding them firmly in place. Perfect!
