I use Thread Heaven to 'condition' my thread. I like it far better than beeswax. It does help but doesn't solve the problem completely. If it's a 'technique' issue then I have the same problem. It think it's just a law of nature. When I run into the problem repeatedly I try to make it a point to pay closer attention and 'unloop' my thread before pulling it tight. Doesn't always help and I end up cutting thread, knotting, burying and starting again. Sometimes I just let it go if there's not a big loop.
