Answer to "My jacket is covered in pine sap, what do I do?"Try lighter fluid. I have used lighter fluid to remove gum from sweaters, jeans, jackets with no residue or problem whatsoever. Dab it on gently and it usually dissolves the gum.
Answer to "How do I wash wool?"I have washed 100% wool and 100% cashmeres in the washing machine..! I use cold water, mild detergent and use the delicate shortest cycle. Remove carefully from washer and I hang by the armholes, reshape if necessary, over the towel bar, or shower curtain bar to air dry. - Takes about 2 days to fully dry. I never experienced any shrinkage. Never put your sweaters on a hangar...when wet or dry...
